Ram Jet 350 PFI
It's the return of the fuelie small-block! The electronic fuel-injection system on the new Ram Jet 350 not only borrows its name from the mechanical Rochester units of the past, but also takes styling cues from them. But despite its retro look, this fuel injection system uses state-of-the-art components developed by GM to give you all of the benefits of modern electronic engine management. According to GMPP, several key characteristics of the Ram Jet are the excellent cold and hot start capabilities, always ideal air-to-fuel ratios, and exceptional throttle response, power, and driveability. And it's hard to argue with 350 hp (at 5,200 rpm) and 400 ft-lbs of torque (at 3,500 rpm).
Another key benefit with the Ram Jet 350 is its ease of installation. The fuel injection's "brains" are stuffed into the industry-leading, easy-to-install MEFI 3 controller, which literally fits in the palm of your hand (it was originally developed by GM Powertrain for marine applications). Below the fuel injection is a roller-cam 350 with four-bolt mains, 9.4:1 compression, and Vortec cylinder heads. The Ram Jet package includes the engine and fuel injection, wiring harness, MEFI 3 controller, and detailed instructions. Once installed in the vehicle, a user needs only to supply 12-volt power, fuel, and, oh yes, the throttle!
Ram Jet 502 PFI
You could call it the king Rat of the 21st Century-the port fuel-injected Ram Jet 502. Harold Martin, a fuel-injected race engine builder and GMPP Pro Mod racer, assisted the GMPP engineering staff in the building of this incredible engine. Together they came up with a great-looking (and performing) intake manifold design that offers the best in fuel management technology. Like the Ram Jet 350, this big-block uses the small, easy-to-install MEFI 3 controller.
The Ram Jet 502 makes 510 hp at 5,500 rpm and 550 ft-lbs of torque at 4500rpm, but the real story is the flat torque curve. The engine makes gobs of torque throughout its operating range, a feat made possible by the large intake plenum and runners (which would never be possible on a carbureted application). In fact, the Ram Jet manifold is so efficient that GMPP was able to make all of this horsepower and torque with a production L98 throttle body assembly. And it still offers street-friendly EFI characteristics like easy cold starts, great idle quality, and instant throttle response. For muscle-minded big-block enthusiasts, choosing this beast is a no-brainer!
The brains of GM's Ram Jet...
The brains of GM's Ram Jet engines are in this engine control unit, the MEFI 3. Small enough to literally fit in your hand, the unit can easily be mounted in the engine compartment (or on the engine itself), eliminating the need to run a huge loom of wiring through the firewall. All you need to attach is a 12-volt power supply.
