• Ram Jet 350


Chevrolet Performance’s unique Ram Jet 350 combines the classic look of the original Rochester mechanical injection system with the dependability and optimized performance of contemporary port fuel injection. It’s the perfect combination for a project vehicle, producing 345 hp and 396 lb.-ft. of torque. Our engineers tweaked the
calibration on this iconic engine, and the result is a broadened torque curve and 22 more horsepower at 5,200 rpm – which means better drivability and power over a broader rpm spectrum than ever before!

A 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 most vehicles without modifications.

The 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.
