Quote: Probably overkill. I think that with aluminum heads and 10.25:1 , pump gas would be O.K. I don't know that there is any more power to be had by using more octane than you need to avoid detonation. You could throw a little more timing at it if it likes it , but unless you are near detonation , I bet 93 would be fine.
Randy I gotta agree with this as I have 10.0 comp with iron 906 heads and I run on 92 pump with no problems at all. I did use the quench pad pistons but unless you plan to run a ton of timing you should be fine on pump. I run 36 to 38 total all in by 2000. Ron
