Last month Chevrolet announced the ZZ632/1000 V8 crate motor. As the name suggests, the naturally aspirated 632 ci (10.348 L) makes 1004 hp and 876 lb-ft of torque on 93 octane fuel. Chevrolet Performance released a video of the motor on the dyno before unveiling the motor at SEMA 2021. If you are interested in swapping one of these, GM Authority reports it starts at $37,758.
