Mr. Moldy

hi everyone I am looking for advice-info-help on a 69 455 i am putting together. It's taken me seven years to gather all I have today. I purchased a offy dual quad tunnel ram for my HO 69 455 which is completely stock right now with a eldebrock manifold and a holley 650. The engine right now is overcarbed with the holley but I am butting the 330 olds engine into the gmc that the 455 came out of. What do I need to do to the 455 for the quads to run well? Cam, lifters, crank? I am a chev builder and the 455 is new to me. I have read this forum for a couple of years now and everone is very knowLEDGEABLE. I look forward to hearing from you and I respect your opinions on this site. Thanks for the help.

I would put the smallest CFM carbs on there that I can find if you leave it relatively stock. You can run a stock lower end with a good cam and head messaging. Talk to some of the other guys running a 455 and see what there combo's are producing.

Mr. Moldy

Thanks for the advice. The engine is out of the truck and
Getting ready to be put in the olds. Why can and lifters would you reccomend. I was thinking 1.6 for the lifters or 1.5?
