What kind of pistons are you using? That looks like it will be a hell of a setup..Mine is pretty close to it but havent taken it to the track yet and wont til i get some traction. I would say 11's or low 12's..If you can keep it to the ground.

I am using probe industries forged pistons.
11's is what i'm shooting for and somewhere in the neighborhood of 450 - 500 horsepower at the flywheel.
