Description
Chevrolet Performance 19434636 LS 454 7.4L Iron Block Crate Engine Performance
This Chevrolet Performance 19434636 LS 454 assembly combines massive 7.4L displacement with the structural mechanical integrity of a cast iron block. Featuring aluminum cylinder heads and a hydraulic roller camshaft, this engine is engineered for high volumetric efficiency and extreme durability. The internally balanced rotating assembly provides a professional-grade foundation for high-horsepower builds requiring the strength of an iron LS architecture.
The LS engine architecture fits 1997–2004 Chevrolet Corvettes and serves as a high-displacement upgrade for 1998–2002 Chevrolet Camaros. It integrates seamlessly into 1967–1972 Chevrolet C10 trucks using standard LS-swap engine mounts. These attributes ensure precise powertrain integration for modern restomod projects, providing a high-capacity 454 cubic inch footprint within the compact and versatile Gen IV LS engine platform architecture.
