Re: My Proposed 383 Build.
the eagle set looks good.... i used scat and i prefer king bearings but thatll work... i used the same cam but i bought the full set of lifters AND cam from comp... the heads arnt bad but if i were you id shoot for some 74ish cc combustion chambers or else your compression is gonna be high... i assume you wanna run pump gas?
you have a great set up! be sure to check rod to wall clearance before your final assembly... i know youre gonna have to grind it off... a dremel works well

You'd better talk to Skip before you order. The cam has more lift than he says the heads will handle.
