    Outrageous style and fuel-injected drivability - all with Big-Block power!

    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.
