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. shruggy

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 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

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 whistling
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 work
Epecially the 275 HP 340 motors devil whistling

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.
