coil-near-plug ignition coils

The Chevrolet Performance ZZ632/1000 Deluxe Crate Engine represents the pinnacle of big-block performance, engineered to deliver 1,004 horsepower on pump gas. This engine is built around a robust, tall-deck Sportsman Bowtie block, housing an all-forged roller assembly for maximum durability and power output. Its displacement of 632 cubic inches (10.35L) is complemented by cutting-edge RS-X design aluminum spread-port cylinder heads, drawing inspiration from Pro Stock racing technology. Key components include a high-performance hydraulic roller camshaft with significant lift (.780"/.782") and duration, ensuring optimal valve timing. The engine features a modern crank-trigger ignition system with coil-near-plug ignition coils strategically mounted on a unique valley plate for efficient and reliable spark delivery. An EFI induction system is integrated for precise fuel control, coupled with a pre-programmed, self-learning control system to optimize performance and drivability. This ZZ632/1000 is sold as a complete assembly, arriving with cylinder heads, intake manifold, oil pan, damper, front cover, water pump, and a 14" automatic transmission flexplate (P/N 12561217) pre-installed. However, specific installation considerations apply: the throttle body is shipped uninstalled and must be fitted by the engine installer. Additionally, users will need to supply their own starter, an EFI-compatible high-pressure fuel pump, and an air cleaner suitable for a 4500-series (Dominator) mounting flange. The unique design of the cylinder head exhaust ports necessitates a custom exhaust system. For manual transmission applications, an internally balanced flywheel is required. This engine is not intended for marine applications. As with many high-performance components, users should be aware of potential California Proposition 65 warnings regarding cancer and reproductive harm.
