Larry - aka, "The Wizard"s 470 Roller motor by TriShield. Pump gas / drive anywhere .. bolt on the street slicks and mid 11's
Larry's while a strong runner is far from.stock looking, stuff gets difficult and tradeoffs in driveabilty are mandatory when looking for solid 11's with stock parts and pumpgas compression
Talk to Gary (Greatscat) - I know he has build some 482s that look stock - sound stock, even with at Q-jet and pull like a freighttrain for resonable money.
