Thanks Rumble and Moper,
I didn't build this engine. I bought it complete from a motivated seller, so I'm hoping for the best. I've just changed a few bolt on items. It was built by Magnum Superchargers in Michigan. Anyone ever heard of them?

Well, it was about as dead as a door nail under/about 3,000 RPM. Then it woke up. Made me pay attention.
What size rear tire are you running?

I want to run a 235/60/15 instead of the 205/60/15s I have now. So going from a 24.6 tire to a 26.1 diamter tire. I may run the BF goodrich drag radial or the MT drag radial in that size for the track. I'm thinking of having a separate set of rear tires and wheels for the track.
