Formula 1 was dual quads-no tunnel rams allowed but I think cross rams were. I passed on a Mickey Thompson cross rams thinking it was no legal-wish I had picked it up for what they are worth now. Formula 2 I think was single 4 bbl, and i think 3 was a 2BBL not sure what Formula 4 was. I think there was no definitive width on slicks as long as they fit in the fenderwell! The 70 and up Cudas had a big advantage there.
