Info

The Ram Jet 502 blends the legendary torque and performance of the Big-Block with a modern port fuel injection system and tunnel ram-style high-rise intake manifold. It’s a combination that offers uncompromising performance in a visually stunning presentation. The unique Ram Jet fuel injection system stands 11 inches tall at its highest point and consists of a two-piece manifold/plenum assembly, eight injectors, a throttle body, and an updated MEFI 4 controller.

Setup instructions are included, making it a simple “plug-and-play” installation. Supporting the unique induction system is a robust bottom end with an all-forged rotating assembly and a smooth hydraulic roller camshaft. The heads are high-flow aluminum oval-port parts from Chevrolet Performance. You’ll need to check your ride for clearance before closing the hood over the Ram Jet 502.
