The Mopar Complete Crate Engine is a 345 HEMI® engine assembly designed to deliver legendary power. This complete unit offers a robust 383 horsepower and 417 lb.-ft. of torque, ensuring exceptional performance. It comes equipped with essential components including a water pump, flywheel and clutch, front sump oil pan, intake manifold with throttle body, fuel injectors, and coil packs. With a 345 cubic inch displacement, a 99.5 mm bore, 90.9 mm stroke, and a 10.5:1 compression ratio, it is built for performance. Premium fuel is recommended for optimal output. This crate engine is intended for installation in motor vehicles manufactured prior to model year 1976 or for competition vehicles driven on tracks or off-road. Vehicles manufactured in 1976 and later equipped with this part should not be driven on public roads or highways, as this may violate emissions laws and regulations. Customers are responsible for ensuring compliance with all applicable federal, state, and local laws. Note that this engine is not equipped with the Multiple Displacement System (MDS). For optimal performance, a customer must purchase the crate engine with an engine controller kit (P/N: 77072455AH or 77072453AG). The engine comes with a 24-month unlimited mileage parts warranty when purchased with a Mopar Hemi Engine Controller kit on the same invoice; otherwise, it has a 90-day parts-only warranty. Ram truck or other applications may require modifications, and this is not a direct replacement for all factory 5.7L vehicles.
