I know the Superbee/RR 383 HP got a diff camshaft than the 383 HP Magnum/supercomando used on the Charger, Coronet, Satellite and as far I know is the only difference, but what are the spec on them?

Is the lower of the purpleshaft cams correct for the 330 or to the 335 hp engine?

It wasn't just the cams; the other difference in the engines was the HP used 440 heads. Sorry I don't have the cam specs - they should be available online.

Edit: Wow, looks like I really stirred things up! Sorry, this is what I was told many, many years ago, and never questioned it. Obviously, it is wrong - please excuse my ignorance.

440 heads? Different from the 383?

no

Different cam, valve springs and exhaust manifolds. 68 to 71 383's all used the same heads as 440's. 67 383's used 516 casting heads, while 67 440's used the 915. 2bbl engines usually had less compression as well.

Ok, would like to know the specs on diff parts between the 330 and the 335 horse power engines

Diff exhaust manifolds between them? I know diff with 2 bbls but being both 4 bbls ? I guess both were called magnum as well ( Dodge )

335 hp engines usually got the HP exhaust manifolds, while the 330 hp engines usually got logs like the 2bbls.

No they don't. 68-70 are the same 906 heads, 1971 are 3462346 heads

No they did not get log manifolds. The 383 4 bbl engines absolutely have HP manifolds 1968-1971, The 1967 and older 383 4 BBl engines in B and C bodies got log manifolds.

Well, I'm looking at several 68/70 Charger engine bays with 383 Magnum and I can see HP manifold exhaust on everyone

Same exhaust manifolds too.

the difference is that the 335 horse engine got a windage tray and the 330 horse engine did not that's the 5 horse difference.

Not true. My 69 383 Dart GTS with 330hp had the windage tray in the oil pan from day one. And I'm the original owner.

Mopar derated the HP on all the 383 A body engines(300 or maybe 305 HP) supposedly due to the driver side exhaust manifold, so they said
Me thinks that the 335 HP rated 390 FE Mustang and Fairlane GT and the 1968 1968 and up 428 ford motors ratings of 330 and 335 HP had a lot of input on Mopars decision on those A body HP rating
Epecially the 275 HP 340 motors

there is no windage tray on 383 A body it has baffles in the oil pan not the same thing windage tray on big block mopars is a tray that goes between oil pan and block, so it is true.

Okay you call it one thing, I call it another. The principal still the same. And I don't believe the so called windage tray made 5 horse power difference. It was in the more restrictive exhaust manifolds.

The FSM shows the same cam and spring specs of the 383 2V used on the Charger 383 4V, but the Charger has 10.0:1 compression vs. 9.2:1 on the 383 2V. It also shows the 383 4V used in the Dart and SuperBee as using the same cam and springs as the 440 4V. I've always seen HP manifolds used on 383 4V Chargers.

It is the windage tray ,the op is talking B bodies and your dart is not a B body the last I checked as my 69 383 gts conv. is an A body so unless dodge built 1 69 gts 383 B body and you got it ,yours is also an A body.

335hp gets the 375hp 440 cam and springs.

The 1970 brochure says camshaft, springs and windage tray.
http://www.hamtramck-historical.com/images/dealerships/DealershipDataBook/1970/70_Barracuda0014.jpg

the reason for this pissing match is the original question is not specific enough to answer the question properly

WHAT YEAR & BODY 383 4bbl VS. 383HP 4bbl are "WE" discussing?

1970?

383 4bbl 330hp blue engine w/CARTER carb (B, C & E-bodies)
VS.
383HP 4bbl 335hp orange engine w/HOLLEY carb (B & E-bodies) ZERO C-bodies

what specifically would you like to discuss ??

The 346 castings were also used on 440's.

Like Dan says. Give him some specifics and he can answer most questions. I've never known him to get anything wrong as far as I far as my knowledge goes. I do have a 70 Challenger 383 SE with the blue 330 horse ( not the RT or HP). It has air and a Carter carb. It has no windage tray, a 402 pan, and hp manifolds. My original 70 Cuda with the orange 335 HP Version had a Holley and hp manifolds.

Yes, I just detailed 68 and 69 ( as an example ) dealer datasheet specs and compared the info between chargers and superbees, and states Chargers got the standard camshaft and superbees got the hight lift ones, along with the diff springs of course

Never thought a 383 magnum charger ( and I guess coronets and Belvederes with supercomandos ) engine got standard camshafts! I always thought all BB magnums got same performance camshafts and sorings, so the same than 440 mkaing the "Magnum" name more standard to all BB meaning same inner parts for everyone. And superbees/RR got a even "higher step" one.

What are the difference between the standard and the "high lifft" camshafts then ?

I guess the first one of the purpleshaft cams is to the 440s and superbees/RR 383s then

Wondering now about the 400 magnums camshafts too

The lift is not that different, like 0.020" more. I have the numbers, just to lazy to go get them. The duration is bigger as well, and the real reason for the performance increase.

None of the "purple shafts" were installed by the factory. The original purples shaft/shafts were a step up or more from what was installed from the factory in wedge motors. I guess now you can purchase a resto cam from MP. Maybe it is called a purple cam too.

The difference?

One is orange the other isn't.

One has a fancy pie plate the other doesn't.

One it said to be 335hp by Chrysler, the other isn't, and this is the point. I'm sure both made their rated HP at some RPM level, but that doesn't mean it's max or that they really are that different in output.

This is my first post here, I had almost this exact question on another site.

SO I have a 69 Charger 383 4bbl A/C 330HP car.
My car is a #'s matching car that is low miles (7,000) and mostly org shape.
It came to me with #'s matching 383 4bbl(Holley)carb, A/C(330HP) engine painted blue(turquoise) and a duel snorkel air cleaner.
It had no pie tin.
My question would be what pie tin should I have,383 4bbl,or 383 Magnum? and do I have the correct air cleaner?
Most 69 383 4bbl A/C cars I have looked up, have the duel snorkel, but I have also come across ever possible combo of color engine and air cleaner and pie tins you could imagine.
SO what is factory correct?
Also what makes the 383 330hp vs the 383 335HP?
I was told it was just the cam, that 383 A/C (330hp) engines uses the cam as the 383 2bbl engine.And the 335hp engine uses the R.R./magnum cam.(just what I was told, I do not know this as fact,just what was told to me)

Could it be the carb?(A/C has Holley vs non air Carter?)
I also would love to know what makes the 5 hp difference between the motors.? And what tin my car should have on it?
Thanks, hope to learn the thing that make the motors different.

I was also told,a while back, that all 4bbl Big block engines in 2nd gen Chargers, were Magnum engines, no matter the color it is painted. Because it was Dodge's performance engine in its performance car, and all A/C car engines were blue,but in a Charger it was called a Magnum.

Again I do not know that to be a fact, I am not trying to argue with anyone, I am just saying what I was told years ago by some guys, I am just trying to educate myself on the matter.

I mean you can't even feel a 5 hp difference in a 330hp vs 335hp 383 anyway, and I think the HP and torque #'s are rated at same rpm on the motors.

Now we're getting somewhere .....

HP manifolds is a misnomer - per CHRYLER they are "DUAL EXHAUST MANIFOLDS"

All HP engines have dual exhaust, all dual exhaust car do NOT have HP engines.

1968 B-body

the only 383HP 4bbl 335hp engines were installed in Road Runners and Super Bees

these engines included the 440HP's cam/valve springs/windage tray

(the Charger & other b-bodies 383 4bbl 330hp had the same cam as the 383 2bbl)

fantasy "pie tins" have existed for decades

every car did not receive one & they were not available for every engine

the 1970 Charger was the first year that all of the 383 4bbl engines used were of the "383 MAGNUM" variety (383HP)

So it is safe to say, in my case because my car is so complete and missing only the org rims(but I got org wheel covers)and it had 70' front seats,and everything else that my car did not have a pie tin on it.
Again I am just basing that on the fact I have most every part for my car,even the jack and lug wrench, and the org carb and air cleaner are there, and that you have said not all cars had pie tins.

So Dan, what you are saying is that the exhaust manifolds that everyone calls HP manifolds are called Duel Exhaust manifolds by Chrysler?
SO any engine with those manifolds IS a HP(MAGNUM) Engine?
And that would mean that no 69 Chargers with 383 4bbl A/C engines had the "Duel Exhaust"(HP)Manifolds?

Might be wrong but the only 383 engine that used a Holly was the 70 all the others AFB-AVS. 2 cams low performance and high performance + 6 barrel type, same specs just different lobe angle. Each engine each year shared the same head just springs where different, (67 had different ex valve size LP to HP) Chrysler did some stupid things but they did keep it simple on this stuff. Way to many 383 Hemi six-packs out there.

Damn! sometimes I forgett I have the direct conection performance book!!

Actually my 74 Mopar parts catalog matches the number posted there for the HiPo camshaft, 3512907 camshaft... used on all 383/400 HP and 440 HP, but this means the 335 383 or 330 383 ? so the 330 383 is not an HP still being a magnum ?

then there is a superseded number for it, 4071002 camshaft one of them I have it NOS on its original box, and is purple.

now... does that number takes to the MP 4452783 ?

then read it better on some other section and the 335 383 camshaft takes the stock 3512907... which by the direct conection book is 268-284 camsshaft with 450 lift... that meets the MP 4452783 spec and the fact the higher camshaft used from factory is a purple one

but still on the previous section talking about stock assemblies, is not clear what is considered a 383 HP to take one or the other being the 330 or the 335 engine.

pics of books later

My 69 383 4bbl A/C car has duel exhaust,with what looks to be factory "H" pipe and hangers and mufflers.
And I now think I figured out the yellow crayon 68 written on the front of my pass side valve cover is not a 68 it is an 899 and one 9 is gone and its written upside down.
I will now have to go see if the pipes and mufflers have any numbers on them so I can figure out this semi-mystery!!!


Also do 383HP MAGNUM ROAD RUNNER 335Horse engines use the same pistons as 383 330horse pistons, or do the 335horse motors have valve pockets in them?
Could you put a "RoadRunner/Magnum" cam in the 330hp 383 with 2bbl cam with out causing any damage? I know my engine(330horse) the pistons almost have a positive deck height at TDC.

well the color change on Magnums is a 69/71 setup, but we had pre 68 engines being magnum and turqoise, same as post 72 being corporated blue... no matter if A/C or not. Thats doesn't eliminate the magnum spec ( or supercommando on plymouths )

ok, this is an oooold file I have had saved and forgott about it untill now, but really dunno how to read everyone of these specs. I think we can find some conclusions here

No,I looked up the numbers on my Holley in the little white numbers books I have and it comes back as a 69 383 4bbl(with a note 570cfm).
I THINK that big block cars with air used the Holley carbs.
Because most every 69 383 w A/C I have looked at had duel snorkel air cleaner and Holley carb. So my car DID org have a Holley, but WHY it did, I do not know I can only guess, the above reason.

Specs are
383 2V, 330HP 4V, and 350HP 440
256°/260° .425"/.435"

335HP 383, and 475HP 440
268°/284° .450"/.458"

Ok, pics of my 74 catalog and DC book

This "prooves" the basic of the Purple shafts is the highest of the production shafts.


Last file is on the DC section talking about the upgrade suggestions

Now That is some VERY helpful info!!!!!!
I will be saving all of those screen shots!!
So it looks as if I may be yanking out my cam and getting a "roadrunner/magnum" cam.


I only wish I could see dyno numbers from 1000rpm-6100rpm on the two different cams(335 vs 330) Just to see how much low numbers you give up switching the two.
Any body have a 330 hp 383 and put in a 335 cam, if so how differently is the car to drive?


Thanks for the above info!!!!!

Now I'm noticing a debate never thought it was to come and it is about the HP exhaust manifolds... which I think is CLEAR all magnum engines were with them.

My main concern is it seems the 335 hp 383 is MORE MAGNUM than the other LOL.

And per the mopar parts catalog, the 400 magnum got the same camshaft than the 383 335 engine, being a lower performance engine

'68 Dodge Specs:

I vaguely recall that number, it was a newer "smog" cam, same lift and duration but altered timing events.

Robert

Not per DC book.

I missed this post!

Thats sounds like the dealer databooks says, but DC book seems to be slightly contradictory

So, any 383 4V is a magnum still with standard cam and springs, and all got HiPo exhaust manifolds. But the 335HP is a magnum "plus"

And any 400 4V is also a magnum BUT they got all the "high lift" cam, still with the lower compression rate. LOL

Well that goes back to what I was told years ago that the 383"magnum" was born by putting the same heads on it as the 440. So by that thinking any 4bbl 383 from 68-71 is a Magnum. So is it just a "Magnum" when the 383/400/440 share heads? Like pre 68 383's had there own head,a 67 383 had its own head,67 440 had it's own head.

And I just wanted to know if Dodge called my 69 383 4bbl/duel exhaust 330hp engine a 383 Magnum or 383 4bbl for my air cleaner!!!LOL
But I love learning Mopar stuff!!!

Well just going by the 1969 Charger sales book, the only engine that has the title MAGNUM attached to it at all is the 440.
So as far as Dodge was concerned I guess its a 383 2Bbl or 383 4Bbl, and the R/T 's 440 MAGNUM.

I thought that if you had a non A/C 383 4Bbl in a Charger it was a Magnum, but going by the 69 sales book nope, never. Only 383 4Bbl was the 330HP one, in a Charger in 69.
And it looks as if (at least the photo in the sales book) duel snorkel, no pie tin.

the reason for this pissing match is the original question is not specific enough to answer the question properly



This urine spraying match comes up about once every year, never gets settled.

No.

The 383-4 335 horse was introduced in 68 with the Road Runner. The difference between it and the 330 horse assembly was, basically, it used the higher lift cam and springs introduced the year before in the GTX and Coronet R/T. The carb was different than the 330 horse as well as the 335 was intended to get a windage tray.

The 906 heads were used on all 68 big blocks. The springs were different with the 335 but not the head casting.
As Dan stated earlier, there are no HP exhaust manifolds. There are two and 4bbl manifolds.

When Dodge brought out the Super Bee mid year, they used the 335 horse assembly and called it the Magnum.

The 335 horse variant of the 383-4 was used from 68-70. The applications changed each year. In 68 only the RR and SB without A/C got the 335 assembly.
In 69, any B body with manual transmission without A/C and the RR or SB with either transmission and without A/C got the 335 horse version. Any 69 B body with A/C got the 330 horse. Any non RR or SB B body (Charger, Satellite, Coronet) with automatic transmission got the 330 horse.

The 1970 applications get a little more convoluted with the use of the 335 horse in B and E bodies. However, there was a 335 horse assembly available with A/C in 1970.

Properly and originally, the term 383 Magnum refers to a 68-70 Dodge with the 335 horse version. Dodge did use the term Magnum on other engines after 1970.

So....
1968: 383 Magnum in Super Bees without A/C.
1969: Manual transmission B bodies without A/C OR a Super Bee with either transmission and without A/C. So no 69 Charger with A/C or automatic would have the 335 horse Magnum.

Magnum is a Dodge term on some engines. Super Commando is a Plymouth term.

Wow so much bad information

Thank you!

I think that if what was said above is true, about the exhaust manifolds, that there is a 2bbl and 4 bbl and there is no HP exhaust manifolds,that has also helped fuel the confusion.
Because everyone says the HP exhaust manifolds were only on HI-Po engines(AKA MAGNUM/ROADRUNNER) And my 69 charger 383(blue 330hp) 4bbl with A/C has duel exhaust and the four barrel exhaust manifolds.
So by seeing the four barrel exhaust manifolds and everyone calling them HP manifolds you would think that I have the HP engine (AKA MAGNUM) when it is really the 330 hp version.
and I would guess that unless you can hear the two engines side by side to hear the different cam shafts(if you can even hear a difference)that you could paint a blue engine orange and slap on the pie tin and then confuse the hell out of everyone!LOL
So I bet the exhaust manifolds added to the issue we are talking about.

I agree.

These guys are probably more knowledgable than me, but I don't think there is such a thing as a "factory H-pipe." Just FYI since you are talking about swapping a cam nobody will ever see for originality...

After all these years is hard to find an all original Mopar from fact, but looikng at this, maybe...

http://bringatrailer.com/2014/03/20/all-original-driver-1968-dodge-charger-383/

Magnum engine? Mmm

Another Charger with 383... Magnum?

https://youtu.be/eApCxdPxLmw

Sellers says is matching numbers and original miles engine. Driver side manifold seems to be HiPo one.

Just because that 68 charger has a 383 magnum pie tin doesn't make it one. So I'm reading a bunch of jibberich..is the concensess that 330 horse has no windage tray? Right?

orange pie tins didn't come out 'til 1970 model year

Nacho....what part has been unclear about applications of the 335 horse assembly in 1968?

What part was unclear about the A/C application in 1969?

Sorry, somehow missed that... no AC on 68/69 383 Magnum/SuperCommandos? soo the you couldn't get a Superbee/RR with AC ?

Was just 68/69 or also up to 71?



Of course I know, but they seems to be born there!

On a side note! ( a bit off topic ) How does the pie tin air cleaner takes the air? I can't find any entry on them

Might be wrong but the only 383 engine that used a Holly was the 70 all the others AFB-AVS. 2 cams low performance and high performance + 6 barrel type, same specs just different lobe angle. Each engine each year shared the same head just springs where different, (67 had different ex valve size LP to HP) Chrysler did some stupid things but they did keep it simple on this stuff.

No,I looked up the numbers on my Holley in the little white numbers books I have and it comes back as a 69 383 4bbl(with a note 570cfm).
I THINK that big block cars with air used the Holley carbs.
Because most every 69 383 w A/C I have looked at had duel snorkel air cleaner and Holley carb. So my car DID org have a Holley, but WHY it did, I do not know I can only guess, the above reason. [/quote]



Per FSM in 69

Incorrect, 330HP engine in 68/69/70 ... which is the engine he asks about ... is a 4bbl engine with what people refer to as the HP manifolds.

did you type that with a straight face ?

[/quote]
You're right, some 70 383 Super Commandos did have Holleys. In 70, I bought a new 70 383, 4 speed 'Cuda with A/C off the showroom at Sam Krug Chrysler Plymouth in Vegas & it had the twin snorkel, black air cleaner with a Holley. First thing I did was remove the A/C compressor to save weight, install headers & a small triangular air cleaner with a foam element that melted into the carb whenever the Holley backfired. Dumb kid I was. Threw a rod thru the block racing my friend's big buick on the freeway & bye bye went the 'Cuda.

Yes you could get a road runner, and supebee, with A/C , it would have the 330HP engine instead of the 335hp .

I haven't seen 69 383 4 bbls with A/C and holleys in 69 , the 4bbl manifolds before 1970 were not holley friendly.

And don't take the LITTLE WHITE BOOK info as gospel, Galen has admitted it has mistakes ...

Did you type that with a straight face ?

no kidding

Someone changed the headpipes on that car, there isn't an H pipe on any 383 Mopar , only on 440hp, 6pk 70/71 and Hemi cars.

The 383 330hp and 335 hp engine in 68 and 69 have the same pistons, .0025 in the hole with NO VALVE RELIEFS, there is only flat top or big round shallow dish pistons in 383's.

Yes you can put the 4bbl cam in your motor and if your pistons are positive deck height then someone cut that block or Chrysler screwed the pooch machining it originally because no 383's have a positive deck height piston from the factory ... you want to change your valve springs also with your cam change, the 4 bbl cam used a spring with an internal flat wire damper spring also.

The crayon mark I don't think is 899, the number is the engine assembly number ... I'd have to do some digging to find out what the 69 A/C equipped 383 engine assembly number is.

No , the principle is not the same, it's not even close, the baffles in the B body and A body pan do not do anything the same as a windage tray.

The baffles are for oil sloshing on accell and decell, the windage tray as made by chrysler, slows the oil getting back to the sump ... but it's supposed to keep the crank windage from foaming the oil

As far as the blue charger for sale in above post:
Well mine is a 69, not a 68, but I THINK that A/C big blocks had the duel snorkel air cleaners(68/69 B-body) So maybe that was changed a while back, because the one he has looks much cooler then the duel snorkel.
Also the fuel line looks to be going to the wrong spot,as if maybe the carb has been swaped?
Again maybe its different in 68 vs 69, but 69 A/C 383 got Holley.

I was told on a different site that 68/69 big block A/C, 4Bbl cars all got Holley carbs.

That may be the fuel line for the Carter?

Back to the other topic:

I don't take the little white books as gospel,just a point in the right direction, but the numbers on my Holley carb come back as a 69, 383 a/c carb, so my car being a 69 383 A/c Charger, I am guessing it the correct (org ) carb. The car is 45+ years old so it could have been changed.
My car has 7,000 miles it was hit hard in driver 1/4 panel over 37 years ago and has been parked from then on, so most of all the stuff on my car looks factory. But anything could have been changed/swapped, I don't personally know.
The build sheet has the engine # as 899 that's how I came to that conclusion about yellow crayon mark on pass side valve cover.
At first,I thought it was a 68, but after looking at build sheet and the valve cover I now think it may have read 899.

too much wrong info/thinking in this one post .....

B-rad, you'd be best to start your own thread giving specifics of your car and the questions you have.

1969 383HP 4bbl originally used Carter AVS carbs ONLY
1969 383 4bbl used HOLLEY carbs with and without A/C
1969 383 4bbl & 383HP 4bbl both originally used dual exhaust manifolds (as pictured below)

yes because there is no windage tray.

I agree with you on what you said above.
But in 69 383 A/C,Automatic Used Holley Carbs #R4440(4160 series)


They did NOT use the Holley carbs in 68.
They also used Holley in 1970 with the N/96 and N96+n95
And 71

I do not know why they did this. And I am not trying to argue with anyone as I am not an expert.
I was told it was just A/C cars in 69, that used the Holley.

My org question was just about 68/69 Chargers and if the 3834bbl(330hp) engine in them was called a Magnum.
I just wanted to get the right pie tin for my motor.
And that question has been answered.

Then some other things poped up that were interesting, I have learned a few things from this thread!!!

Here is an OK acrticle on it.
Nice chart towards the end.
http://www.hotrod.com/articles/mopp-0111-chrysler-oem-carburetors/

Johnrr did you type that jibberish with a straight face lmfao

Those pics I gave where from a 1969 factory service manual, the only Holly it listed was a 440 and if I'm not mistaken only for a c-body.
Being from that time era and working for my uncle's Dodge dealership, my understanding was the 300-330 hp engine had the more restrictive a-body manifold and the 335 hp the other one. Have to ask Rhino if one of his 383 Darts came with the windage tray in 68-69. My m-code 440 has the tray and the a-body pan. Always thought that tray was worth more than 5 hp. Besides 330 was at 5000 and 335 was at 5200, that 200 could equal 5 hp. Just a numbers game

yes, just read that, but it seems on 69, not in 68

no need for that, you can get an hp curve going down or flat from 5000 instead keep growing

mid year change on B bodies ?( but SB and RR ) is not on dealership databooks... or I missed

in any of the cases... optional or standard on this setup ?

If you rebuild the engine non of this stuff matters. You're going to replace stuff and upgrade things. So if no windage tray for example, you'll add one or do a crank scraper. And so on. Pistons cam etc same deal. If you have logs, in the trash they go.

If you are talking "original" purple shaft, I think your dot connecting might be flawed.

What Direct Connection and Mopar Performance called "Purple Shafts" back in the 1970s started with the "Hemi Grind", I believe, followed by the 484 and 292, previously Racer Brown SSH-25 and -44 respectively. As years went by, the family of "purple shaft" grew and at some point added the replacement cam you have. I don't recall anyone in the 1970s or 1980 calling the factory cam a "purple cam", or running out to by one.

Could be mistaken.

The original direct Connection Chrysler HP street cams that where non Racer Brown, Crane and Cam Dynamics race roller cams for the wedge motors where the infamous "Street Hemi 284 Purple Shaft" grind that made absolutely no manifold vacuum and didn't work worth a hoot IMO I sold one to a customer, garage owner and friend of mine that put it into a original 1968 Dodge Charger 383 330 HP car with a 727, I went over to his shop one night and helped him degree it in properly, I also made sure later that it started right away and was broken in properly. He drove the car around the block once and pulled that cam out and bought and installed R.V. cam so the car would stop more than once in traffic, the car belong to a 18 year old kid that wrapped it around a power pole in less than three months after getting the car back from the engine over haul
I've used some of the Mopar OEM replacement cam kits for SB like the 1968 340 automatic that they use to sell, it work okay
Iskys, Comp Cams, Lunati and other cam brands I can't think of right now worked better

899 auto and A/C
897 four speed with A/C

Yes, you could get the RR or SB in 68 with ac. You got the 330 horse engine.

69 B bodies with manual tranny and no ac got the 335 horse. Not optional, not mid year change. Plants like standardization and easy. Having a 330 horse manual no ac was a bit of overkill. It would be just as easy to use the 335 horse manual version rather than assembling a 330 horse manual version.

Dealer books don't get into specific applications.

Ok... so more less in conclussion these are the basic ( waiting to be corrected yet ) at least for 68 and 69... 70 and 71 s are a kinda diff story what we haven't talked completelly yet. Some questions still on this post.

383 2 bbl
Standard camshaft standard valve springs, no windage tray, low compression pistons, dual snorkel air cleaner, standard exhaust manifolds.... cast or forged crank ? I think all got still forged in those years. Tourquoise paint. I guess single timming chain

383 4 bbl 330
Standard camshaft standard valve springs, windage tray ( still debating ), high compression pistons, dual snorkel air cleaner, HP exhaust manifolds ( seems to be a standard agreement but still some doubts ), forged crank. No Magnum/supercommando denomination so, no HP stamp? Turquoise paint, I guess double timing chain ?

383 4 bbl 335
High performance ( 440 Magnum ) camshaft, valve springs with dampener, windage tray, high compression pistons, pie tin air cleaner, HP exhaust manifolds, forged crank. Magnum/supercommando denomination so, HP stamp. Orange paint from 69 but still turquoise on 68 ? Of course double timing chain.

Camshafts specs were posted allong the thread and the Magnum one is the MP purpleshaft one, the first one of the list. DC book adds a bit of confusion on the info thought.

Then we have another details floated on here like the cars they came in, carbs used, which got AC and which not, what were good adds yo the thread I wasn't really asking initially but is ALLWAYS good to know. I guess some other differences could be around like the bearings used on ones or the others.

I guess the valve springs are different NOT just due the dampener but the specs itself are also different... harder and stuff...

I think the orange paint on all magnum/supercomando engines began in 69, right?

A bit off topic I added another question and it was, WHERE takes the air the unsilenced ( pie tin ) air cleaner? I can't find any opening on them!

Need to add some notes about what I told about purple shafts.

I'm not saying the magnum cam was called purple shaft back in the days, but it is now and since sometime in the past ( what I can't tell ). I was calling it on the way is actually.

Need to say however, the superseded 4071002 production replacement cam, which I have one NOS on its original factory/dealer box, not being MP or DC labeled thought just regular Chrysler logo and Mopar print on box ( like any regular replacement part ), OF THE 3512907 production for HP engines ( stated on my 74 Parts catalog like that but I guess an earlier PN on earlier catalogs, something like 28xxxxx ), IT GOT purple paint. I have the pic of the camshaft somewhere posted. Can't say the ones original installed on engines from factory got the purple finish or if DC book would call it Purple shaft, but the replacement parts dealer piece I have got the purple finish. Aaand meets the MP 4452783 specs, plus the MP catalog descriptions it like the Magnum replacement, being purple.

EDITING, this is an ooooold thread on dc.com where I posted the PN cross reference when I bought the camshaft. Maybe some other numbers are missed on the way up to the last MP one. Pics are there and you can see the purple finish on the one I got.

Magnum/Supercomando camshaft PN crossreference

On the air cleaner, air comes in from the bottom edge, the cover is a larger diameter than the base. No cast cranks till the 400. I'm not positive but I think I remember seeing a pinkish- purple mark on the stock hipo cam too. The two springs are different, got both. My book shows two 383 engines in 69, 2 & 4 barrel, 2 bbl got the small cam 4 bbl got the big cam, it shows Barracuda and Road Runner having same engine. Couldn't find anything about the windage tray. Been a long time, can't remember all the stuff.

From 68-70, there are two versions of the 383-4. The 330 horse and the 335 horse. The install applications vary by year.

Books and websites, generally, do not cover in detail the various applications for each year and assembly.

Boy,all this for 5 hp,glad it isn't 50 hp !!

Lol, not about 5hp, but just the correct setup on each one... informative thread

Gotcha, just detailing some dissasembled cleaners at nicksgarage website and can note now you mention the base is just about the filter element diameter due the recession shape I seeing, and the top supports over the element not over the base, then get an extra room after the support area for it.





Pretty sure on 70 and 71 383 2 bbls got cast

Non HP in 71 but forged in 70.

Humm. I do have a 71 fury in the back with the 383-2 bbl. I'll that check out. Factory service manuals are pretty thorough.

Per damper table here, it seems also 70s

"383 4 bbl 330

I have a 69 Charger, H-code, 330 horse 383. Was 95% original when I got it. Engine is turquoise, not stamped as an HP motor. Factory HP manifolds, small round 340/383/440 HP air cleaner (no snorkels) with red 383 4-barrel pie tin . Standard 4v intake, and of course the car has A/C. I think the 69 manual states a specific carb...compared to HP stamped 383's (like 6 numbers listed). Did not have a double roller chain.

When I pulled the heads, they had red valve springs, and factory details that it had a standard 2v camshaft.

Essentially, it seems its a 2v- base motor with nothing more than a 4v intake, and HP exhaust manifolds. And all should have had AC.

And flat top pistons instead of dished.

ikr. All to go as fast as a Nissan Altima. lol.

"And flat top pistons instead of dished."

Yes, mine is in the garage with original pistons. Did a basic rebuild/re-ring. Tall flat tops.

I scanned through the posts in the thread and didn't notice anyone mentioning the fact that the 69 335hp 383 motor had positive deck height flat top pistons originally. It wasn't much but it kept anyone from just doing a quick bolt on of the 67 440 closed chamber heads to increase compression. You had to make sure your head gasket was thick enough to keep the piston from hitting the combustion chamber. When rebuilding the engines in the 70's, the catalog had a listing for both pistons, neutral and positive height. Consider this as a possibility as to why the horsepower rating was different. Eventually the taller pistons were just dropped from the books and like now only one is shown.

I recall this was one of the tips mentioned in the big yellow Direction Connection Racing Manual.

Perhaps Plymouth converted to the open chamber heads for emissions or some other Federal Mandate and the piston change was a little cheat to help performance.

If you mention that, somebody will insist that they weren't +dh, so I never say anything.

How much over DH got your pistons?

( yes somebody mentioned about that )

Did 2bbl engines get dished instead lower CH pistons? I thought they were simply lower ones.

How much + have you measured them?

Long ago, far far away. It was less than .100 , if my yellow book surfaces I will check to see if it mentions it.
