Hi all - I have a few noob questions. My 62 Bel Air Wagon has, what I can only assume, is a stock 327. It has the 250hp heads on it. I have an aluminum intake (no name) with a 1406 carb and headers. Just info in case its relevant. So, according to the manual, the compression should be 10.5/1. Whats the proper fuel octane to run? I can run 87 without pinging. I know on newer cars at this CR you’d want a higher octane. But I’ve been following the if it don’t ping, you’re good rule. 2nd - would this engine be a flat tappet or hydraulic lifter? I’m thinking of trying Amsoil as I do lose about a qt every 2k miles and I’m thinking a better than Napa oil might have better evap properties. I do not see any noticeable smoke from the exhaust. So I’m trying to determine if I should try zrod but they don’t have that in 10w40 and 20w50 seems too thick? Their syn oil is available in 10w40 but Its a different additive package.
