I quit reading (and walk away...) when I see that rules contain the phrases "small block" and "big block".

[Flyin79bird]

Those are X275 rules, not Ultra Street.

Yeah, you run into that in classes that are not Pontiac only...

In x275, yes, because the weights listed a Pontiac combination would be using nitrous, probably via a fogger.
