Motivating the Willys is a 406ci small-block V-8 with an estimated output of 480hp and 510 lb-ft of torque. To get this kind of power, Montpas is running Speed-Pro hypereutectic flat-top pistons with 12:1 compression, RPC aluminum heads, a Comp Cams roller cam, and Holley HP MPI fuel injection. A MSD 6AL box and MSD distributor handle ignition duties, while dual Optima RedTop batteries keep the engine running in the event of an alternator failure. The engine exhales through 2.5-inch Flowmaster mufflers. The whole thing is backed by a stout Muncie SM465 manual transmission.
