Chevrolet Performance ZZ632/1000 Deluxe Long Block Crate Engines

Chevrolet Performance's ZZ632/1000 deluxe long block crate engines are their biggest and baddest big blocks! They start with a tall deck Sportsman Bowtie block and an all-forged roller assembly, then add a hydraulic roller camshaft and high-flow spread-port CNC-machined cylinder heads derived from Pro Stock racing technology. The RS-X design cylinder heads feature symmetrical ports to produce similar power from all eight cylinders. ZZ632 crate engines have a crank-trigger ignition system with coil-near-plug ignition coils mounted on a unique valley plate. Included is a pre-programmed, self-learning control system for precise fuel control and amazing output on premium pump gas. These big block engines reach peak power at 6,600 rpm and rev to a recommended maximum of 7,000 rpm.
