Chevy Ram Jet 350 - Port Fuel Injection

GM Performance Parts has just what you need to put a modern twist on your favorite classic hot rod with our amazing Ram Jet 350 crate engine. GM offered the Ram Jet fuel injection system on a variety of models in the late-1950s through the mid-1960s, but the Ram Jet has never looked as good as it does in the Ram Jet 350 crate engine.

Adding fuel injection to a carbureted engine has never been easier. GMPP Ram Jet 350's are ready to hook up as a kit with most everything you need. Just install it and hook up the fuel injection system with the directions supplied. The Ram Jet 350 has a styled intake plenum that feeds a state-of-the-art, electronically controlled port fuel injection system. Developed by GM to the same standards as production vehicle systems, the Ram Jet 350 delivers exceptional throttle response and performance. This is made possible by the sophisticated, latest-generation MEFI 4 controller, which has improved electronics and closed loop capability (compared with the previous MEFI 3 system) for great all-around drivability.

The Ram Jet 350 is built for long-lasting durability and pump-gas compatibility. Vortec cylinder heads, a hydraulic roller camshaft and 9.4:1 compression round out the spec's on this 350 engine.

GM Performance Parts includes the wiring harness and detailed instructions. This engine can be installed on any 1976-or-earlier vehicle originally equipped with a carburetor.
