Free Shipping!

The Chevrolet Performance 502 Ram Jet Engine is unlike any other big block you've experienced. Chevrolet engineers designed the unique large plenum Ram Jet intake that produces a broad torque curve. 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 intake manifold. It's a combination that offers awesome 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.
