I know there's a ton of info and I've gone though countless hours of searching. I'm running a 31 model a 4 banger.complete Rebuilt enginewith 5:1 high compression head, centrifugal advance new distributor, 12 volts, full headers, and Riley dual carb intake with dual Holley 94's. My question is to those who are running a dual carb intake on a 4 banger what jets and power valves are you running? And how does it run. From what I have read I plan on going with 3.5 power valves and maybe 46 or 48 jets. Thanks.
