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.
