RAM JET 350
Modern performance with vintage style
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.
We’ve taken our 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.
We deliver the Ram Jet 350 with the following components to make it easier to install and start:
- Unique intake manifold and plenum that is 9.75 inches tall — plenty of clearance to fit under the hood of most vehicles without modifications
- MEFI 4 engine controller
- Wiring harness
- Detailed instructions
The bottom end of the engine is our stout 350 with a brand-new block, a hydraulic roller cam, Vortec iron heads, and a pump-gas-friendly 9.4:1 compression ratio.
