Roush DL588SREC 588 CI Street Race Electronic Fuel Engine

Description

Stop severe equipment downtime with the Roush DL588SREC Crate Engine, engineered for commercial long block repower projects that demand massive big block Ford cubic inches. This 588 cid 9.6L engine produces 700HP at 5,900 RPM and 720 ft-lbs torque. Technicians must verify front frame rail width because large 385 series cylinder head profiles widen exhaust header spacing.

Solid ASTM A48 Class 35 cast iron forms the heavy 4-bolt main engine block. A forged 4340 chromoly steel crankshaft pairs with forged H-beam rods inside this Roush engine core. The heavy 12V starter motor draws 200A during cold crank tests. Dry weight measures 680 lbs across dimensions of 32in length by 29in width by 31in height. Pan capacity holds 8.0 quarts.

Key Features of Roush DL588SREC

Fleet operators buy Roush DL588SREC Crate Engine packages to accelerate heavy industrial engine rebuild schedules. The electronic fuel injection system meters precise fuel charges into high port intake runners.

• High port aluminum cylinder heads feature CNC combustion chambers that optimize flame propagation.
• An aggressive hydraulic roller camshaft provides broad power bands without requiring manual lash adjustments.
• Electronic throttle body fuel injection self tunes fuel delivery under changing atmospheric barometric pressure.
• Forged 2618 alloy pistons resist structural deformation under severe high combustion temperatures.
• The DL588SREC commercial core holds 0.0020in rod bearing oil clearances under severe dynamometer testing.
• Cross bolted main bearing caps prevent crank bore flex under heavy rotational torque loads.
• Multi layer steel head gaskets clamp down tightly to eliminate combustion bore leakage.

Dynamometer Load Bench Test Limits

Dynamometer testing confirms 700HP at 5,900 RPM plus 720 ft-lbs torque at 4,400 RPM for this DL588SREC long block engine. Pressure sensors track 62 PSI oil gallery pressure at 2,500 RPM while maintaining 195°F coolant operating temperature. Combustion chamber compression measures 195 PSI across all eight cylinders within 3% balance. Crankshaft journal runout checks show 0.0003in TIR across main journals. Exhaust pyrometers register 1,320°F during extended test sweeps.

Shop Installation Maintenance Protocol Requirements

Throttle linkage setups demand 6 lbs return spring pull force to ensure positive valve return. Fleet mechanics must avoid this heavy duty replacement engine for vehicle chassis lacking reinforced suspension crossmembers or vehicles without high volume electric fuel pumps delivering 58 PSI continuous pressure.

• Drain break in crankcase oil after 500 miles or 20 run hours then install fresh 15W-50 synthetic oil.
• Inspect electronic fuel injector seals for leaks before initial high pressure fuel priming.
• Check cylinder head fasteners at 85 ft-lbs torque following the initial thermal heat expansion cycle.

Crate Manifest Warranty Protection Coverage

The Roush build standard includes a 2-Year or 24,000-mile limited manufacturer warranty. The secure crate contains the complete engine, electronic fuel injection system, fuel rails, ignition distributor, water pump, harmonic balancer, oil pan, plus certified dynamometer test sheets.
