Jeff- So lets look at a car that has no engine rules. Dirt Late Models have only two engine rules: No Ti rods and one 4 barrel carb, thats it. So why do you suppose BB's haven't been competitive in the class for twenty years, especially considering how much more power a single 4 barrel BB makes than a 4 barrel SB?
I'll note that as a younger kid I was first attracted to these cars because I was heavily biased towards BB's.
