Thanks yall...everything happens so fast I'm surprised I've done as well as I have when it has stood up!

Wes...it's basically a 4500 Sledgehammer plate, but I'm using the NOS Pro Race solenoid instead of the Trashcan. I'm spraying 300 hp right now, but have tunes up to 485 hp. If I go any further I'll need to change the cam. If the front end will stay down and I can get after it pretty good, this thing will go faster than I ever intended on just the 300 jetting. So I think I'm good for now, lol.
