All Makes 10.5s only (w's ok) Multiple Carburetors (no Dominators) 3,000 lbs. min. weight Obviously N/A period hoodscoops Engine style must match year of car. No pony cars (Mustangs, Camaros, post '68 Cudas/use body styles accepted by majority of NSS groups) NSS interior rules
Basically accepted NSS rules with min. weight, 10.5's, trans brake/two steps,and a pro tree.
Keep it simple.
I like but the tires should be any size since NSS has a restriction...
