Roush DL511RFEPC 511 CI Race FE Performance Crate Engine

Description

During intense summer track day sessions, the Roush DL511RFEPC Race Performance Crate Engine stays planted while producing 625 horsepower at 6,000 RPM. Displacing 511 cubic inches on a Ford FE block, this carbureted platform features polished aluminum component packages combined with race-spec valvetrain hardware for competitive vintage motorsport classes.

A premium cast iron FE block featuring cross-bolted main caps anchors the rotating group. Mechanical specifications include 4.375-inch cylinder bores, a 4.250-inch stroke, a 4340 forged steel crankshaft, 4340 H-beam rods, and forged 4032 aluminum pistons. Operating at a 10.8:1 compression ratio with a polished seven-quart road-race oil pan, dry weight registers at 612 lbs.

Key Features of Roush DL511RFEPC

Engine builders buy Roush DL511RFEPC crate engine units to attain track durability with elite visual craftsmanship. Polished billet brackets and aluminum rocker covers resist engine bay corrosion under intense heat cycles.

• Polished single-plane intake manifold delivers balanced fuel distribution to all ports
• 4.375-inch iron cylinder bores support high cylinder pressures without distortion
• 4.250-inch forged stroke crankshaft endures brutal high-RPM track stress loads
• 6.490-inch forged H-beam rods resist bending under heavy inertia loads
• 10.8:1 forged pistons tolerate continuous high combustion temperatures
• Polished cast aluminum valve covers protect dual valve springs and roller rockers
• Billet aluminum accessory brackets maintain proper belt tracking under hard load
• DL511RFEPC balance specs maintain crank train equilibrium past the 6,200 RPM mark

Carbureted Combustion Dyno Output Metrics

Operating between 2,500 and 6,500 RPM, this V8 develops 625 brake horsepower at 6,000 RPM and 600 lb-ft torque at 4,400 RPM. A mechanical roller camshaft features 246 degrees intake and 252 degrees exhaust duration at 0.050-inch lift, alongside 0.620-inch valve lift. Operating on 93-octane premium pump gasoline, it draws 11 in-Hg manifold idle vacuum and holds 50 to 70 PSI oil pressure.

Chassis Envelope Mating Fitment Standards

The classic Ford FE bellhousing bolt pattern matches Tremec TKX, Magnum, and Ford C6 automatic transmission cases. Internal neutral dynamic balance requires zero-balance flywheels. The road-race oil pan drops between tubular crossmembers and steering linkages on custom pro-touring frames.

Initial Break-In Operating Restrictions

Before primary starter engagement, flood all internal galleries using a mechanical pre-lube tool pressurized with SAE 30 high-zinc petroleum oil. This high-compression unit is not intended for marine raw seawater cooling, 87-octane fuel, or boost beyond 8 PSI on standard ring end gaps.

• Dump the initial break-in petroleum fluid following the first 50 miles of run time
• Swap engine oil every 3,000 miles using specialized high-zinc performance formulas
• Inspect pushrod straightness and rocker bolt torque every 12 months

Factory Warranty Coverage Complete Manifest

The DL511RFEPC includes a 24-Month or 24,000-Mile manufacturer limited warranty for non-sanctioned street competition use. Physical contents include the dressed race long block, polished oil pan, polished intake manifold, high-performance distributor, ignition wires, and an authentic dyno sheet.
