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

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. Set-up 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. Then again, it looks so impressive, you may just want to cruise around with the hood off.
