Trying to discuss rules with NMCA is an exercise in futility. Tell me again why a 4150 billet carb body of correct dimension isn't legal in an Index class? According to them "it has a distinct advantage over a casting" In fact its the ONLY part made from billet that is illegal in the class. However Methanol is legal. I shake my head.
