Like I said, you are looking for way too many money races to lose to a 13 second car. And dont go into the whole stock bottom end thing. I dont care about a stock bottom end. Upgraded pistons, rods, and bearings dont make power (well maybe a few) unless your changing the bore or stroke. They just handle the power you are making better. I guess you wont say what you REALLY run now, might hurt "business" I'll still run ya for a 20 spot at the track. From the looks of things I'll lose, but I guess I've blown 20 on dumber stuff .
