70-71 e-bodies aren't NSS type cars. Never have been, never will be. You might as well allow big block 67-69 Camaros... "All Makes/All Models"??? You might want to clarify that. I also don't like the carb rule. Multiple carbs should be required in my opinion... Not much nostalgic about a single Dominator.

A new class name not including NSS is needed. You've gotten away from NSS big time.
