Roush 5.0L SR Coyote Crate Engines DL50SRC

DL50SRC is Roush's factory-supercharged Coyote long block, new at 302 cubic inches, pairing a hydraulic roller camshaft and 9.5:1 compression ratio with a block and heads cast from aluminum and internally balanced for boosted duty.

What's supercharged and assembled

The supercharger bolts on at the factory, and the fuel injection hardware, throttle body, computer, and wiring harness ship with it, so the EFI side of the engine is largely plug-and-play. Also fitted: the oil pan, the valve covers, the harmonic balancer, the timing cover, and the water pump, while the flexplate, flywheel, and air cleaner are not included.

Where this fits

Roush positions this engine for modern muscle car builds, street projects, and Coyote swaps that want factory-calibrated supercharged power without sourcing and tuning a blower kit separately. Because the exhaust system and cooling components beyond the water pump are not included, and no distributor is needed thanks to the EFI setup, plan your remaining drivetrain and cooling parts before ordering. Roush recommends premium fuel for this compression ratio, and the factory tune is calibrated specifically around the installed supercharger.

Common questions

Does it come with an ECU? Yes, a factory-calibrated computer and wiring harness are included.

What transmission hardware is included? None; there's no flywheel or flexplate, so that hardware is sourced separately based on your transmission choice.

Does the supercharger need a separate tune? It's factory-calibrated as a package, so the base tune is matched to the blower from the start.
