19432060 ZZ632 Chevrolet Performance ZZ632 Crate Engine

 Availibility First quarter 2022

 

Chevrolet Performance’s ZZ632 takes the legendary Big-Block to all-new thresholds
of displacement performance. It’s the largest Big-Block we’ve ever built—and with an
incredible 1,004 horsepower and 876 lb.-ft. of torque on 93-octane pump gas, it’s also
the most powerful!
The ZZ632 starts with one of our tall-deck Sportsman Bowtie blocks as its
foundation, adds an all-forged roller assembly, a hydraulic roller camshaft and
all-new, high-flow spread-port cylinder heads derived from Pro Stock racing
technology. An EFI induction system provides the precise fuel control to enable
the crate engine’s stunning output with pump gas.
Our Deluxe package comes complete from the oil pan to the throttle body, as well as a
crank-trigger ignition system with coil-near-plug ignition coils mounted on a unique
valley plate, plug wires, water pump, balancer and an aluminum single-plane intake
manifold. The assembly also includes Chevy Orange valve covers with the “632” logo.
