Roush Industries Inc. Crate Engines BD427IRC

A Roush 427IR crate engine (part number BD427IRC), a naturally aspirated 7.0-liter block built with a high-performance cast-iron block and aluminum heads, internally balanced, for buyers assembling their own induction and ignition system around it. What this crate engine includes The engine ships assembled with a high-performance hydraulic roller camshaft, a 1-piece rear main seal, and an induction system, along with the oil pan, valve covers, and timing cover installed. It does not include a carburetor, throttle body, distributor, water pump, harmonic balancer, flexplate, flywheel, air cleaner, spark plugs or wires, computer, wiring harness, or supercharger, so plan to source a fuel system, ignition, and cooling setup to finish the build. What to check before buying Because this is a bare, race-oriented long block rather than a turnkey engine, confirm your planned fuel injection or carburetor setup, ignition system, and tuning plan are ready before the engine arrives. Premium or race fuel at 91-octane or higher is recommended, and the engine is not emissions-certified, so it is intended for off-road, racing, or custom-build applications rather than a direct street-emissions-compliant swap. Common questions Does it come with a carburetor? No, a carburetor is not included. What's the displacement? 7.0 liters, or 427 cubic inches. Is it supercharger compatible? It can be paired with an aftermarket supercharger or turbocharger setup. Specifications Feature Details Brand Roush Industries Inc.
