But only if you attach the intake and exhaust that they used to rate that motor on the brake dyno. The LS7 and other crate motors are used in other chevy products that have different ratings for the same motors in different models of cars based on the type of exhaust, shape of exhaust pipes to get around obstacles, type, shape, and size of intake.
When a manufacturer sells a crate motor, they can attach anything they want and rate at the bhp measured. They can also just bypass that testing and give you the bhp it measured when it was measured for an actual vehicle. I've seen manufacturers to both. But that's completely irrelevant here because ........
Manufacturers rates cars by the power the engine actually makes at the motor shaft in that model of car based on how it's configured. Manufacturers often give different ratings to the same motor when sold separately based on what was bolted to that motor at the time. But we're not buying electric motors. We're buying a vehicle that has a horsepower claim as it is delivered from the factory.
Way back in the day, before SAE standards were put in place to prevent this kind of fraud, manufacturers would dyno their motors with open exhausts, intakes, without accessories attached like ac compressors, alternators, and such, and then claim the car made that horsepower even though it didn't. They're not allowed do to that anymore. They have measure the motor with *exactly* what is going to be attached as inputs and outputs.
