The new undisputed heavy weight champion, the Ram Jet 502 crate engine from GM Performance Parts makes 510 horsepower at 5500 RPM and 550 ft-lbs of torque at 4500 RPM. GM engineers and Pro Mod racer Harold Martin combined together to design the unique large plenum Ram Jet intake that produces the broad torque curve using only a L98 throttle body assembly. Instant throttle response and tire smoking torque! Note; the oil pan installed on this crate engine will NOT fit a Camaro or Chevelle chassis.

Note; the GM oil pan will not clear the Camaro or Chevelle chassis, SDPC offers several different oil pan kits to fit your particular application. A different oil pan can be installed at our facility prior to shipping for a small additional charge.
