Description

Dominate the drag strip with raw, naturally aspirated big block displacement using the Roush SF511RFEC 511 CI Race engine. This 8.4L monster builds upon a heavy-duty aluminum FE block packed with a forged steel crankshaft and an SF-specific low-profile oil pan. Breathing through high-flow CNC aluminum heads and a single-plane race intake manifold, this 600 HP crate engine delivers the authentic, tire-shredding big block Ford race experience for specialized racing chassis.

Key Features of Roush SF511RFEC 511 CI

• SF-Specific Low-Profile Pan: Engineered perfectly to clear the restrictive steering subframes on specialized classic Ford chassis.
• 600 HP Dyno-Proven Output: Leaves the factory fully hot-tested to guarantee massive race-level horsepower and unstoppable low-end torque.
• Single-Plane Race Induction: Arrives equipped with a high-flow aluminum intake manifold ready to accept a massive 4-barrel racing carburetor.
• Aluminum FE Engine Block: Significantly reduces front-end vehicle weight compared to an iron block while drastically increasing structural rigidity.
• Forged Rotating Assembly: Packs the massive block with a forged steel crank and H-beam rods to handle brutal track acceleration safely.
• Solid Roller Valvetrain: Provides extreme valve lift and duration without the high-RPM valve float associated with hydraulic setups.

Fuel & Ignition System Requirements

Feeding a 511ci performance race engine requires a massive fuel delivery setup and a hot spark.

• Bolt on a high-CFM 850+ 4-barrel race carburetor and feed it with a dedicated high-volume electric fuel pump system
• Connect the included MSD distributor to a high-voltage MSD 6AL ignition box and run heavy-duty spark plug wires

Installation Break-In Oil & Priming Instructions

Follow these setup rules to keep your new 511ci solid roller engine healthy for years to come.

• Use a priming tool through the distributor hole to get oil flowing to the solid roller lifters before turning the crankshaft
• Fill the low-profile pan with conventional high-zinc 10W-40 break-in oil and run a varied RPM cycle to seat the forged rings
