so what is the best way to do say a pcv system and what is the best carb. obviously a spread bore. i have a stock spread bore off a 1975 455 pontiac. some giant sized car i forget the name. i called it the green pickle. wouldn't that be a good one? i scored a stock 4bbl intake already too. would that work ok with these stock log exhaust manifolds? should i get a dual exhaust too or could i leave it single?
well, dual exhaust and headers are typically the most straight forward bang for the buck performance mods you can make. most other performance mods will hurt low rpm performance but headers and dual exh drop back pressure and usually help performance across the entire rpm range.
the poncho quadrajet is probably a decent place to start but i'm sure you'll need to tune it in.
i should have kept it to just the pcv system and where to tap into the intake/carb. a tee is the only thing i can think of. i forgot i have a thread for that and it got answered PERFECTLY and yes i guess i am going to devirginize my engine and put the 4bbl carb on just so i have a vacuum source for the pcv, but i got a stock 4bbl intake last year and that carb off the Green Pickle so i just have to fashion some kind of bung for the pcv valve in the downdraft tube hole and i'll be squatin i high cottin!
