One hit and done. Wow I love derbies and plan on finding a 5th ave with a 318 to get back into the action. There boxy and seem to do well. Ultimately I would love to find a car to enter into a 'Frank the Tank' class. No welding, no reinforcements. Chain or wire everything up and go out with the biggest car and more importantly an engine that will live so hot there is fire coming out the exhaust tubes.
