Also thought of another good contact--Randi Lyn Shipp.
She makes all the National events, and probably knows most everybody running Stock & Super Stock, on a national level.

I noticed that she's on the SS pre-entry list, for the up-coming national event, driving a 4th gen Bird, with 428 Pontiac power. But, it's not listed as a GT car. So, I don't know if it really has Pontiac power or not.
J.B. Clegg is also on the list, with his 9 sec SD455 '74 Bird.

Lynn McCarty & family also race Pontiac powered GT cars. They may know where something is.
