I have entered the Bomber class at a local track here in Houston. Below is the rules pertaining to the engine. Last season, 2007, I ran basically a stock Jasper type 355. Nothing special, same motor you would put in the family truckster.

Next year I want to step it up. My machine shop is throwing out all sorts of ideas but I don't want to spend the money on a motor and be on the edge of legality. Loopholes don't bother me but I want to be legal so if I'm torn down I pass.

Thoughts????
