Those are the ones you cc'd at 64 right?

If you can do 2-wheel burnouts, you are good to go, forget the compression test,lol.

Yes those were the ones i CC'd at 64 before cutting 0.45. Surprisingly the teener before i swapped manifolds and heads would lay rubber in first and second gear with 3.55 gears. So i am excitied to see what that teen will do now.
