Oh thats interesting. There are "rules" about which class the motors fall into? Which sanctioning bodies apply them?

In AA fuel I wouldn't think it matters. In dirt track it might. Does it actually make any difference in what "class" a guy might run? Or is it more of a way of keeping track of who's running what? I would guess cubic inches would apply in some classes regardless of who was classified as the engine architecture.

Could NASCAR run a KB motor in any car?
