The engine I am running is a 68 327 Chevy 300 HP. I have put a 350 crank in and bored .030. I have the camel hump heads with the small valves and flat top pistons.
I think my compression ratio is about 10 to 1. I am not sure. I run 93 because I have tried 87 and had a lot of ping. I run as much timing as I can , about 10 initial with a total of about 38 plus 10 vacuum. It also comes in very early. My biggest thing is I want as much power and gas milage as I can get.
Thanks for the link I will read it all. No matter how much we know there is still a lot to learn !
Thanks, Rick Harris
