Rusty, I'very stated before most of my knowledge is more from reading (a lot of reading) than real life experience
Cars I've done before mainly been a few bolt on like high rise cam, headers, and from my cousin late model and uncle top alcohol and a lot of hot engines my other uncle has built for various people around town.
If my info is misguided advice how so??
I see a lot of people on this forum that build High compression engine to only later try to figure how to get them to run on pump gas that's why I said the 9:1 comment. And the race comment is of course depending on the situation but if you have to detune your engine compared to the other guys to run pump gas more than likely your probably not gonna be as competitive.
