Last year, GM announced a "COPO" Camaro variant with an outlandish 9.4-liter big block V-8 . That option lasted just one year, but for good reason: Chevrolet is now offering the car with their 10.3-liter ZZ632 crate motor .
Although the horsepower numbers for this specific application have not been announced, GM said in November of 2021 that the 632 cubic inch engine produced an absurd 1004 horsepower on pump gas, with 876 lb-ft of torque to go with it for good measure. In addition to the engine easily beating the size record for a V-8 offered in a factory-built Camaro set last year, the 10.3-liter engine should also be the most powerful V-8 offered in a Camaro. It is one of three options available on 2023 COPO cars, sitting above a 427 cubic inch naturally aspirated engine producing 470 horsepower and a 350 cubic inch supercharged engine producing 580.
All three COPO Camaro variants are sold with a bill of sale and are not road legal, so this is not exactly a top-of-the-line Camaro road car and should not be expected to be as cohesive a package as the ZL1 road car. If you absolutely need 632 cubic inches of V-8 in a factory Camaro, you can order the car directly from Chevrolet Performance .
