Super Duty was the name Pontiac used on its high performance (i.e. race ready) engines in the early 1960's, and the Super Duty 455 was a street legal race prepped engine. All SD-455's were hand assembled, and had a reinforced block, casting provisions for a cam driven dry sump on back of the block, special cam shaft, aluminum forged pistons. This Super Duty Trans Am has recently completed an extensive, nut-and-bolt concours restoration by famed builder Roger Dengel of Dengel Restorations in Lewistown, Montana.
