As Jason said the rules say NOTHING about pump gas, so kiss your 16lbs of boost BS goodbye! It also says stock heads, but doesn't state whether or not they can be ported.:wink: Under these rules I know of a GN here in South Florida with a stock bottom end, stock ported iron heads, and a 67 turbo on 28" tires and stock suspension that has been 9.59 @141mph.
I am warning you, your ignorance can be dangerous.:wink:
