Now on to reducing pinging to where you do not need to use a special gasoline blend?
You still might want a higher flow fan.
I am planning a different fan , maybe. I want to drive it a bit and make sure all is good. before doing anything else cooling system wise .
As far as reducing the race gas mix thing. THAT'S gonna require a complete tear down and new pistons. Thats a project for a day down the road a ways. Its not an everyday driver so $100 fuel tank fill ups dont really bother me to much .
