I have no idea of engine size. I made the assumption it would be 406 Cu In. or so similar to NHRA stock and Super Stock basic rules. I may be completely wrong on that. (I should follow my own rule, NEVER assume). I just looked up the rules for the class. They allow HUGE engines! 560 CU in for all but Fords. They get the gift of 620 Cu in. So no idea of the size of Tiemann's Firebird. I doubt it's a 400. Sorry for my incorrect information.
