ENGINE PULLEY KIT

The BluePrint Engines 632 c.i. Pro Series Stroker Crate Engine (Blackout Reaper Edition) is a high-performance GM Big Block-style engine designed for race applications, engine swaps, and custom vehicle builds. This fully dressed engine produces 815 HP and 775 FT-LBS of torque and comes complete with high-end components including a Holley GEN III Ultra Dominator carburetor, forged rotating assembly, and Pro Series cylinder heads.

This crate engine features a tall-deck cast iron block with 4-bolt mains, a 1-piece rear main seal, and a forged crankshaft with a 4.750-inch stroke. The engine is configured with a 11.0:1 compression ratio and includes a hydraulic roller camshaft with .698/.698-inch lift, providing robust power across the RPM range.

This is a universal-fit component intended for custom installations. Installers must verify engine bay clearance, as the tall-deck design is 0.400 inches taller and wider than a standard block, and features 0.300-inch raised exhaust ports which may require custom headers or engine mount adjustments.

Engine is intended for off-road/race use only and is not compliant for use in pollution-controlled vehicles. Professional installation is recommended to ensure proper cooling, fueling, and drivetrain compatibility with the vehicle's specific transmission and chassis constraints.
