Raceparts adds the RDI 427DE to our comprehensive line of large-displacement small-block engine packages. This is a Drivability Enhanced version of the RDI engine Package #8 with the same 4-bolt main block, forged rods and forged crankshaft with 2.750" main bearings. Specially prepared cylinder heads and dual-plane manifold provide more than adequate torque and horsepower with better performance in slow traffic driving. Still the weight is 85 pounds less than the FE iron block and 135 pounds less than the 460 iron block engines.

All new Ford Racing Performance Parts (FRPP) and aftermarket components have been carefully selected, assembled and tested to provide performance for the track and superior tractability for the road. Assembly is by experienced, professional Ford race engine builders using quality components provided and controlled by RDI. The engines are complete, dyno-tuned and ready to install in your Superformance Mk III.
