Well..... Yes and no. We are making about 640 at the crank and we have logged about 6K since April of 06. Granted, we didn't up the HP from 390 until sometime in June or July. That being said, I have never pushed the car to its limmit. Maybe we will if Hot Rod ever has their open track smackdown event. Or maybe we will take it on drag week next year. Driving (these cars) is so much fun, I cannot ever imagine building a trailer queen. Drive um till they drop, rebuild um and drive it some more. Glad to hear you are having fun. Enjoy it while you can.
