National Event Sportsman Teardown Announcement

[Steve Polhill]

Comp is allowed any internal Modifications,as is Top alcohol. If I set a record they pump the engine and check for illegal equipment and done. If NHRA wants to pull a Piston in my DOHC Comp car they are going to have a fight on their hands.

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.

At Noble points race they had Bourgeois pull a head to check bore and stroke, bore spacing, injector size, rear tire width and wheel base. At Tulsa they had Rampy, Hildalgo and I believe Pitt and Stanfield pull a head.
