moper is right. The other factor in my son's car is that folks would be amazed at how little we actually spent to build it and race it. If we had one limitation it was horsepower as we built a good handling street car that he wanted to autocross. We had a ~400hp big block in a 3,400lb car going against ~500hp small blocks in 2,700lb cars that were also physically smaller (first gen Mustangs). We still held our own and due to number of events, won the CP class for the season in the local SCCA chapter. A stock oiling system is what eventually doomed this effort (i.e. spun rod bearings from lack of oil in the corners).
