Just last week, Chevrolet Performance unveiled the ZZ632, the biggest, most-powerful crate engine the brand has ever offered. Now, we have new pricing information on the monster motor, which starts at a suggested retail price just under $38,000.
Per a recent online listing from Gandrud Chevrolet in Green Bay, Wisconsin, the new Chevrolet Performance ZZ632 starts at $37,758.72. However, Gandrud Chevrolet currently offers it on sale through its website with a listed price of $29,499.
That certainly isn’t chump change, especially for a performance crate motor. Nevertheless, the ZZ632 Big Block justifies the cost with a long list of impressive features and specs, starting with the output. Peak horsepower is rated at 1,004 ponies at 6,600 rpm, while peak torque is rated at 876 pound-feet at 5,600 rpm. Both figures are on 93-octane gasoline. Redline is recommended at 7,000 rpm.
That’s a lot, especially from a naturally aspirated engine. The raw cubic inches make the ZZ632 a whopper of a drag racing motor, and according to Chevrolet Performance, a single example of the engine endured more than 200 simulated drag racing passes on a dynamometer during the development process.
The ZZ632 is based on a cast iron block with CNC-machined aluminum heads. Standout features include four-bolt main caps, a forged steel crankshaft, forged steel connecting rods, and forged aluminum pistons, with the compression ratio set at 12.0:1. The iron block shares the same mold as Chevrolet Performance’s ZZ572, with bore increased 0.040 inch, and stroke increased 0.375 inch. Eight electronically controlled port injectors provide the fuel.
The heads incorporate an RS-X Symmetrical Port design with symmetrical intake and exhaust ports to ensure that all eight cylinders yield similar power output. There’s also a billet steel hydraulic roller camshaft, crank-trigger ignition system with coil-near-plug ignition coils mounted on a unique valley plate.
The new Chevrolet Performance ZZ632 crate engine will be on display at the 2021 SEMA Show in Las Vegas next week, while deliveries kick off next year.
