If you don't already know Mike Rohrbaugh in Cincinnati I'll have to put you in touch with him. He's my buddy with the Laguna Seca blue car that's stupid wicked fast in his. He's stock motor / exhaust / etc, gutted, ground controls, sways, etc. Really simple setup but really very fast in it. Turns :38's - 39's on BFG's.
Also, inspect that sub frame and plan on doing the reinforcements if it's not already done.
