im going to a test and tune tommorow and i'm curious if it would be worth buying some race gas and mixing with 91 to give me a higher octane...would this be benifical or pointless?
my mods are in my sig...thanks guys!
If it does not detonate with 36* of timing, you will not gain anything. Even 36* is a little high. It seems 34* is about all most motors need with modern heads.
From what I have read and heard, you should use the lowest Octane your motor will allow, as higher Octanes actually burn slower and can cause a loss of HP in cars that don't need it. There was a test in a car magazine some time ago iwth dyno tests proving that.

Your fine with 91 or 93 pump gas. I learned the hard way after wasting my money on race fuel for a whole season until I learned that my car actually ran the best on good old 93 pump gas. I'll run some 100 low lead AV through it every once in awhile.
i actually dont know my compression ratio, maybe sombody here can help me figure it out. i was running 9.5:1 with the stock 65 cast heads. now i have the edelbrocks with a 60cc chamber. is it possible to figure out compression ratio with this?
