What grade of gas should I burn in my 67 s code 390? I seem to remember reading somewhere that it required premium, I can't find that info now...will 89+ octane do?

thanks for the link...probably could have found that myself! I really need to learn to utilize the available tools better.
sounds like I'll just need to set the timing to the grade of gas I decide on using.
bmaker.
