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 ?? 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.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

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.

Thanks, hope to learn the thing that make the motors different. 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 )
