Gas Question, What effect?

Coyote Jack said
I have a little better than 10.5 to 1 compression with my LA/Magnum hybred. I don't have any pinging with 16 init and 34 total timing running 91 octane. What I am wondering is, what effect would running 100 or even 112 octane race gas have on power? I'm not worried about fuel milage as the diffence in price would more than eat up any mileage savings.

That's exactly what I just timed my 9:1 '92 Commando 360/300 to. Funny, I used to hear that 36-37 total was optimum for these engines, but that seems just too much for mine. But I would think you'd get pinging with 10.5:1, unless you had aluminium heads. You sure you are not?
