Bill Payne is the founder of Straight Up Racing—an independent monster truck racing team based in Port Orchard, Washington—and has recently debuted a new vehicle, dubbed the “Major Payne”. Adapted from a WWII tank, it’s far from your average monster truck.

The Major Payne is modified from an M5 Half-Track Personnel Carrier—produced from 1942 to 1943—though the only original elements remaining are the tracks, suspension, and rear drive axle. Twelve thousand pounds of weight was dropped in the build, which took over a year to complete. A custom-built reverser box provides the tank with remarkable agility, allowing it to safely pivot on its back idler—offering the illusion of wheelies without risking spinal damage for the driver.

A big-block Chevrolet engine with JE pistons, AFR cylinder heads, and a Weiand 8-71 blower furnish the Major Payne with a whopping 1,100 horsepower. The tank is also decked out with a high-flow K and N air filter and performance oil filter.
