Just when you thought the LS series of GM engines had rendered the big-block Chevrolet obsolete, GM engineers had someone hold their beers while they dreamed up the new ZZ632, the most powerful crate engine GM has ever offered.

Power numbers are phenomenal at 1,004 horsepower at 6,600 rpm, with 876 pound-feet of torque at 5,600 rpm. It also noteworthy that this motor is naturally aspirated, with a cast iron block, aluminum heads, a square-bore throttle body with port fuel injection and crankshaft-triggered ignition.

The engine also uses eight coils mounted beneath the intake on a bespoke valley pan never before seen on a “porcupine” engine. Naturally, the crank, rods, pistons, and rockers are forged. Valves are titanium, and the maximum recommended rpm is 7,000. Wow, what a mill, and you can use Google to find deals on pre-orders online for first quarter 2022 delivery for $29,500.
