Roush Industries Inc. Crate Engines DL511IRFEPC

At 8.4L (511 cubic inches), the Roush 511IRFEPC is the largest engine in this lineup, built on a high-performance cast-iron block with aluminum heads and an internally balanced, precision-machined rotating assembly aimed at high-RPM racing and extreme street builds rather than a mild daily driver. What's installed A high-performance hydraulic roller camshaft and one-piece rear main seal anchor the build, with valve covers, a timing cover, and an oil pan already fitted and a harmonic balancer in place. The intake manifold is not included, nor are the carburetor, throttle body, distributor, computer, or wiring harness, so fuel delivery, ignition, and tuning are left entirely to the builder, with aftermarket forced induction an option if you want to add it later. Before you order Given the displacement and the components left out, this engine suits someone set up to handle custom fuel, ignition, and ECU tuning rather than a direct bolt-in replacement. Professional installation and premium or race fuel are recommended, since the compression and camshaft here are built for serious output rather than mild street use. Common questions Does it include a supercharger? No, but the architecture is compatible with aftermarket forced-induction setups if you want to add one later. What's the largest engine in this family? At 511 cubic inches, this is the biggest displacement offered among these Roush crate engines. Specifications Feature Details Brand Roush Industries Inc.
