I am thinking of building a car to run at Rockingham. I am from Florida and our rules arent even close so I have a few questions. It says steel firewall and floorpan, does this mean stock or can it be replaced. Shocks, stock mounting or external. Intakes, cast iron, do they have to be stock? Any rules on trailing arm or a frame bushings? Since there are really no engine rules im assuming full porting and polishing are legal, no crankshaft or rod rules? From what I am reading I assume the 406 is the most popular engine, what about cams are guys running the 450 hydraulic or the larger cam and adding weight.
Thanks for any help
