Tom wanted to build a real 455 Super Duty and spent nearly two years acquiring the parts. "By the end of 1996 I had gotten all the parts to build the motor. I found bits and pieces all over the U.S. and spent lots of money doing it," says Tom. Once together, the 0.030-over 455 (a 462) took the place of the car's original 400. The four-bolt block, crank, rods, and heads are gennie '74 SD items and are accompanied by a custom-ground Rock 'N' Roll Engineering cam with a 0.530 lift and 232/237 duration. Standard Poncho 2.11/1.77 valves are moved via Crane 1.65:1 roller rockers. Even the top of the mill is Super Duty derived with an NOS intake and an 800-cfm Q-jet carb. Spark is provided by an MSD 6AL and an HEI with a sleeve to fit the Super Duty block, while exhaust is removed by Hedman headers, a Dr. Gas X-pipe, and Flowmaster mufflers.
