Hey Guys, Got a few questions for you Olds heads,
1) what size carb is prefered for a stock 72 350 with headers and 4 bbl intake? Right now I've got a 600 Holley on her which seems fine but I'm wondering if a 650 would be better for more performance.
2) I just got some really cool old style Holley valve covers with the knock outs still intact....do I really need to run a breather cap on these? Why can't I put a breather cap on the oil fill tube and call it good?
