Now with NEW MEFI 4 Controller with O2 Sensor!

You may recall the Ram Jet brand from the GM mechanical fuel injection systems of the 1950's. Back then everyone wanted a "fuelie" and today that's even more true. GM Performance Parts has brought back the Ram Jet name with its all new electronic port fuel injection systems for both small-block and big-block Chevy crate engines.

The small-block Ram Jet 350's intake manifold is styled like the Ram Jet of yesterday, but that is where the similarity ends. The all new Ram jet 350 uses state of the art components developed by GM to give you all of the benefits of modern electronic engine management. Who better to fuel inject your hot rod than the people who build 5 million fuel injected cars and trucks per year, including the one in your driveway. Unlike some aftermarket systems, Ram Jet offers great cold starts, hot starts, always ideal air to fuel ratios and exceptional throttle response, power and drivability.

The all new 350 horsepower Ram Jet 350 from GMPP makes it easy to have electronic fuel injection on any vehicle originally equipped with a carburetor. The secret is the industry leading MEFI 4 controller. This new controller fits in the palm of your hand and was originally developed by GM Powertrain for marine applications. MEFI 4 is ideally suited for use in street rods, street machines and sportsman racers. Installation is simple; the Ram Jet 350 is an assembled 350 crate engine with Vortec heads, Ram Jet induction system, wiring harness, MEFI 4 controller, and detailed instructions. Once installed in the vehicle, a user needs only to supply 12V power and fuel. Please note the fuel pump recommendations in the Ram Jet instruction manual.

The Ram Jet 350 has it all, great nostalgic styling, drivability unsurpassed by carburetors or aftermarket fuel injection, power to spare and a hot rod idle that sounds like Woodward Avenue in 1969 all over again! GM Performance Parts is "More Than Just Power" and once you've driven a Ram Jet you'll understand why. The 350 HO is not intended for marine use, and should only be used in 1973 and earlier pre-emissions street vehicles or any year off road vehicles. This engine offers great drivability, reliability, and a nice exhaust note.
