For the puller who wants a little more "zip" in his

In light of the various different approaches to horsepower
in this class, the ITPA has written the rules to ensure
parity for virtually everyone that competes.
Injected big blocks, blown small blocks, and carbureted
small block engines all operate on a playing field made
level by various limits on weight, supercharger size, etc.
