Roush DL511IRFEPC 511 CI IR FE Performance Crate Engine

Description

Harness massive big block displacement through the Roush DL511IRFEPC Individual Runner Performance Crate Engine in your bespoke project car. Generating 650 horsepower at 6,000 RPM from 511 cubic inches, this aluminum FE platform combines eight-stack electronic fuel injection with polished exterior components, creating an engine bay centerpiece engineered for competition and show car display.

Cast from 356-T6 aluminum, the deep-skirt FE cylinder block houses cross-bolted ductile iron main caps for extreme crankshaft stability. Mechanical dimensions include 4.375-inch bores and a 4.250-inch stroke, forged 4340 crankshaft, 4340 H-beam rods, and forged aluminum pistons. Featuring a 10.5:1 compression ratio and a polished seven-quart oil pan, total dry weight equals 528 lbs.

Key Features of Roush DL511IRFEPC

Discerning vehicle craftsmen buy Roush DL511IRFEPC crate engine systems to secure supercar output with vintage Ford styling cues. Mirror-polished intake runners and billet valve covers provide enduring corrosion resistance.

• Polished eight-stack induction system meters air through independent intake runners
• 356-T6 cast aluminum block reduces front axle curb weight significantly
• 4.375-inch cylinder bores allow unshrouded airflow around large intake valves
• 4.250-inch stroke forged 4340 steel crankshaft produces brutal low-end twisting force
• Forged 4340 steel H-beam connecting rods endure high reciprocating stress loads
• 10.5:1 forged pistons permit operation on 93-octane premium pump gasoline
• Polished aluminum front-drive brackets secure cooling and charging equipment
• DL511IRFEPC engine control software maps ignition curves without hesitation

Dyno Verified Output Operating Parameters

Spanning an operating range between 2,200 and 6,200 RPM, this V8 outputs 650 brake horsepower at 6,000 RPM and 620 lb-ft torque at 4,200 RPM. Camshaft duration measures 242 degrees intake and 248 degrees exhaust at 0.050-inch lift, alongside 0.600-inch valve lift. Designed for 93-octane pump gasoline, the engine generates 13 in-Hg idle vacuum while keeping 45 to 65 PSI hot oil pressure.

Chassis Installation Engine Bay Bounds

A classic Ford FE 6-bolt bellhousing flange supports Tremec TKX, Magnum, and heavy Ford automatic transmissions. Internal zero-balance engineering requires neutral balance flywheels. The custom oil pan drops between frame rails on Shelby roadsters and vintage fastbacks without steering drag link interference.

Pre-Oiling Protocol Prohibited Applications

Circulate zinc-rich break-in oil through all internal oil galleries using an external drill tool prior to turning the starter. This power plant is not engineered for marine water cooling, continuous boost beyond 8 PSI on factory ring clearances, or pure alcohol fuels.

• Flush initial zinc break-in petroleum lubricant at 50 miles of run time
• Renew motor lubricant every 3,000 miles using high-zinc synthetic racing formulas
• Inspect throttle body synchronization settings every 12 months for balanced operation

Factory Warranty Coverage Complete Manifest

A 24-Month or 24,000-Mile factory limited warranty protects this powertrain against component failures. Crate contents comprise the complete aluminum long block, polished eight-stack fuel system, ECU, harness, polished oil pan, valve covers, distributor, and certified dyno test documentation.
