Vintage Style and Modern Performance

Free Shipping!

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 electronic port fuel injection.

They took their proven 350 Small-Block and topped it with an exclusive port fuel-injection system that emulates the look of Chevy's factory fuel-injection systems from the 1950s and '60s. It's the perfect choice for a resto-mod hot rod from the original Rochester era.

A brand-new 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 9-3/4'' 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. Some additional components are required, including a high-pressure fuel pump and front accessory drive system.
