I have to agree with bill32. My friend builds cup motors for a living. He built the motor in my car. He also owns a Cobra. It has nothing close to the engine he builds everyday and I know he would not even think about it. Those motors are designed and built to the very ragged edge and only to last 500 miles or whatever the track size is. He works for one of the larger teams that supplies engines to other teams and the the cars they field and none of them are exactly the same.

He did build a very similiar to a cup motor for my cousin for his NASA car and it is definetly a different motor. You know when he is coming before he gets there because it sounds so different, but it only goes well when its wide open. It has such a radical spirit I would hate to drive something like that on the street, it just could not be any fun in traffic. But if it's what you want?
