Get rid of the quadrajunk carb (keep it, but shelf it) put on a Carter AFB carb.. 650 or 700 CFM
If you are going back with orig 455 and keeping it pretty much stock, i would opt for the 650CFM , good thing about them is you can re-jet without disassembly...
you will have way fewer probs from Carter than the Rochester....trust me. They work great. They even come chromed !
(FYI- Edelbrock carb is a Carter with Edelbrock nameplate )
