Nothing in the catalog relates to the current GM NASCAR race engine, the R07 (google it for more info on the current engine). It came after the SB2.2 that you can get heads (18 degree IIRC) and et cetera for. There are used 2.2 engines and parts on The R07 has nothing in common w/the current production engines as far as parts from one working on the other.

The other manufacturers also have their own race-only NASCAR engines.
