My rule book is a little old, and I don't have it with me in Ak, but I would guess that in the SCCA you would be H Stock, or F Street Prepared. I doubt that those cars would be competitive in either class, but so what. Its a lot of fun. H Stock is the slowest class, I think new Mini non supercharged are currently the fastest thing in it, so... I run my '68 Ford Cortina 4 door in F Street Prepared. The golf's etc. kick mu butt.
