1,004 horsepower. 876 lb-ft of torque. A crate to open up and find it all inside.

That's the new Chevrolet Performance ZZ632 now available from your Chevy parts counter.

“The ZZ632 sits at the top of our unparalleled crate engine lineup as the king of performance,” said director of the Performance and Racing Propulsion Team, Russ O’Blenes. “It delivers incredible power, and it does it on pump gas.”

The ZZ632 includes a cast iron block, four-bolt main caps, a forged steel crankshaft and connecting rods, and forged aluminum pistons. The compression ratio is 12.0:1. The iron block shares a mold with the Chevrolet Performance ZZ572 crate engine, with the castings machined out to the impressive 632-cubic-inch displacement. Bore is up 0.040 inch, while stroke was increased 0.375 inch. Both the block and connecting rods were modified to accommodate the extra-long stroke. (Source: GMAuthority.com)
