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...

Magnum engine? Mmm

Another Charger with 383... Magnum?

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