Chevrolet Performance - ZZ632/1000 Crate Engine - Information & Specs

There are a lot of aftermarket performance part options out there, but only a few that are designed, engineered, tested, and backed by Chevrolet. Today I want to give you an overview of our ZZ632EFI crate engine so you can better plan your project. There's an old saying that says there is no replacement for displacement, and the ZZ632EFI certainly delivers on that point. With 632 cubic inches, this modern-day bowtie bed block produces over 1,000 horsepower and over 860 pound-feet of torque on 93 octane pump gas. To achieve this outstanding performance, this tall-deck bowtie is topped off with a new cylinder head design with raised and spread intake ports and free-flowing exhaust ports that are not restricted by production design limits. Delivering the fuel-air mixture is a new design high-rise port fuel injection intake manifold topped off by a 4500 series throttle body. Our performance engineers took the big block crank-triggered ignition from the Chevrolet Performance Parts Bin and adapted it to the PFI system that utilizes coil-near-plug technology from newer design production engines. A unique valet cover has coil mounts that tucks the coils under the intake manifold and keeps them out of the way, which minimizes the length of the spark-plug wires to provide a clean, sleek appearance. The internal components include a high-quality forged steel crankshaft, forged steel connecting rods, and forged pistons that work together to deliver big power for a long time. I hope this quick look at the ZZ632EFI bowtie big block crate engine from Chevrolet Performance helped you learn a little more about how it might be the perfect fit when you are planning your next project. Make sure that you measure your vehicle for cylinder head and air cleaner clearance. The ZZ632EFI big block is physically larger than any other crate engine from Chevrolet Performance and may result in interference in some vehicles.
