Just how quick were the 273 Commando's in the Quarter-Mile.

"It was nothing really radical," Dave, the owner of Koffel's Place in Huron, Ohio, admits today. "When we first started out with it, nobody was sure how it'd work; it looked good on paper. We began with a Racer Brown cam and an Edelbrock intake with two inline Carter carbs on it, so it was pretty mild, and even like that, we set the record right out. Ultimately, we put Webers on it, using a hand-fabricated intake manifold built by a friend of mine named Joe Tribus, who was really good. We also put a Racer Brown roller cam into it, then Harvey built us a nice Crane roller setup that really worked well, and Jere Stahl built some real headers for it. It had the factory standard forged-steel crank and steel rods at first, but with our engine speed, we blacked a few crank journals and finally put aluminum rods in it.

"The heads were 273 heads with 392 Hemi valves, which had been homologated with the NHRA. The valves were way bigger than what the cylinder bore was, so we built a fixture and put these great big 'wart eyes' on the cylinder wall tops. We also milled the surfaces to get the compression back up. The funny thing was the rules allowed you to put these big valves in the heads, but you were not allowed to port them. So you had this basic five-angle valve job, and then you had to get away with whatever you could do on the dogleg angle in the port."
