Roush Industries Inc. Crate Engines DL347IRFSPC

Unlike the carbureted-or-EFI-ready engines elsewhere in this lineup, the Roush 347 IRF SP (DL347IRFSPC) comes with its fuel injection system already tuned and installed, pairing a 347 cubic-inch small-block Ford with performance cylinder heads and a performance hydraulic roller camshaft for a more turnkey power delivery. What's on the engine Spark plug wires join the spark plugs, timing cover, valve covers, oil pan, and harmonic balancer as factory-installed items here, along with the cylinder heads and the fuel injection hardware itself. A supercharger is not part of the build, and neither are the flexplate, flywheel, exhaust manifolds, air cleaner, computer, or wiring harness, so the ECU and exhaust system are still on the builder's list. Fitment and fuel This small-block Ford displacement is a common fit for classic Mustangs and similar performance builds, but confirm your drivetrain and ECU setup are compatible with the installed injection system before ordering rather than assuming a direct match. Roush specifies premium fuel at 91 octane or higher for the camshaft and compression used here. Common questions Does it need a separate ECU? No ECU or transmission ships with this engine; both must be sourced to match the installed fuel injection. Is this engine carbureted? No, it is fuel injected rather than carbureted, which sets it apart from some others in this range. Are spark plug wires included? Yes, both the spark plugs and their wires are fitted at the factory on this engine. Specifications Feature Details Brand Roush Industries Inc.
