The centerpiece of Chevrolet Performance’s booth at this year’s SEMA Show will undoubtedly be the automaker’s newly introduced ZZ632 crate engine. 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.
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.
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. 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.
As 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. It’s not clear if the engine seen in this video is this exact engine, although it seems likely.
It’s worth pointing out this engine is fitted with a pair of silver-painted valve covers and not the orange-painted valve covers that were pictured on the engine in the press photos. As far as we know, the engine will ship with the orange valve covers and not these silver ones.
The performance-obsessed people behind the Hoonigan YouTube channel are currently working on a ZZ632-powered third-generation Chevy Camaro, which will be present at the SEMA Show and will likely be one of the first vehicles equipped with the new crate engine. We’ll have full details on the Hoonigan build once SEMA kicks off next week, but for now, check out the video embedded below to hear the motor in action.
