Ram Jet 350 Crate Engine
351 hp @ 5,000 rpm / 403 lb.-ft. @ 3,600 rpm
Vintage Style and Modern Performance
Chevrolet Performance’s unique Ram Jet 350 combines the classic look of the original Rochester "Fuelie" mechanical fuel injection system with the dependability and optimized performance of contemporary port fuel injection. It’s the perfect combination for a resto-mod hot rod.
The GM cast-iron engine block is matched with a durable rotating assembly that delivers a pump-gas-friendly 9.0:1 compression ratio, as well as a smooth hydraulic roller camshaft that complements power delivery with a great idle quality. The engine’s unique intake manifold and plenum is 9.75 inches tall, offering plenty of clearance to fit under the hood of your street rod, muscle car or truck without modifications.
The Chevy Performance Ram Jet 350 crate engine kit includes a MEFI 4 engine controller, wiring harness and a detailed instruction guide to make adding this retro-style EFI system a complete DIY project. Additional components are required, including a high-pressure fuel pump and front-end accessory drive system.
