It’s not clear if the engine seen in this video is this exact engine, although it seems likely. It sounds mostly like every other Big Block Chevy we’ve heard in the past, although this video allows us to hear what it sounds like when it hits its rather high redline of 7,000 rpm.Īs we pointed out when the engine debuted last week, a single example of the ZZ632 endured over 200 simulated drag-racing passes on a dynamometer during development. This video doesn’t really tell us anything about the ZZ632 crate engine that we didn’t already know, but this is the first time we’ve heard the engine running and under wide-open-throttle.


We’ll likely learn a little bit more about the new Chevy ZZ632 crate engine at the SEMA Show next week (which GM Authority will be attending), but in the meantime, General Motors has placated our Chevy-obsessed minds with a video of its massive new Big Block undergoing some calibration testing on an engine dyno. With a price tag of about $38K, this monstrous 632 cubic-inch crate engine has already generated a ton of buzz online, and with 10.3 liters of displacement, as well as a head-spinning output of 1,004 horsepower and 876 pound-feet of torque, it’s not hard to see why. The centerpiece of Chevrolet Performance’s booth at this year’s SEMA Show will undoubtedly be the automaker’s newly introduced ZZ632 crate engine.
