Steve,
There are still many things that can be checked in Comp such as making sure they run the correct size/type of carburetor. Pumping the engine for claimed cubic inches and also, to make sure they run the correct engine bore spacing. The rumor mill says there have been instances of some guys running small block Chevy engines with 4.50" bore spacing in classes were they must run the OEM, 4.40" bore spacing.
