VEGE DFEP 3.9L 238ci Car Truck Long Block Remanufactured Crate Engine

Description

During demanding urban fleet delivery shifts, the VEGE DFEP Remanufactured Crate Engine 3.9L 238ci long block provides unyielding propulsion. Generating 193 horsepower at 4,500 RPM and 225 lb-ft torque at 2,800 RPM, this pushrod V6 rebuilds commercial vehicle stamina. Enhanced deck resurfacing and heavy-duty lower intake seals stop traditional fluid migration, ensuring dependable performance throughout grueling work shifts.

Solid cast iron 90-degree block architecture houses cross-bolted main bearing caps securing a precision-ground nodular iron crankshaft. Powdered metal connecting rods support hypereutectic pistons across a 3.810-inch bore and 3.500-inch stroke. Compression ratio measures 9.3:1 for regular pump fuel. A stamped steel rear-sump oil pan holds 5.0 quarts, with total dry weight at 410 lbs.

Key Features of VEGE DFEP

Fleet operators buy VEGE DFEP crate engine units to keep cargo vans and service vehicles operating without mechanical failures. Every remanufactured long block undergoes exhaustive spin testing and pressure checking to guarantee zero fluid leaks and dependable oil pressure right out of the crate.

• Split-port cylinder heads enhance fuel atomization to deliver maximum torque across lower engine speeds.
• 47 mm intake valves flow broad air volume into combustion chambers during continuous city hauling.
• DFEP car truck packages incorporate upgraded intake sealing faces to eliminate internal coolant leaks.
• Billet internal balance shafts cancel engine vibrations to reduce driver fatigue during long shifts.
• Micro-polished crank journals establish broad hydrodynamic oil films under severe cargo loads.
• New hydraulic roller lifters eliminate valvetrain tap while reducing parasitic mechanical drag.
• Hardened timing chain sets ensure long-term valve synchronization under heavy stop-and-go driving.

Combustion Chamber Dyno Characteristics

Covering an operational RPM spectrum from 1,200 to 5,000 RPM, this engine outputs 193 peak brake horsepower at 4,500 RPM with 225 lb-ft torque at 2,800 RPM. Camshaft duration runs 186 degrees intake at 0.050-inch lift, with 0.440-inch gross valve lift. Tuned for regular 87-octane pump gasoline. Manifold vacuum holds steady at 19 in-Hg at 650 RPM idle, with hot oil pressure between 40 to 60 PSI.

Chassis Clearance Transaxle Integration

The rear block pattern attaches straight to Ford 4R70W and 4R75E automatic transmissions without adapter hardware. External balance requires matching weighted flywheels or flexplates. Sump contours drop cleanly around steering linkages and suspension crossmembers, providing generous room for exhaust pipes, starter motors, and chassis wiring harnesses.

Maintenance Protocols Operating Boundaries

Pressurize internal oil galleries with a pre-lube tank before starting the motor to protect bearing surfaces. Pour 5W-20 mineral motor oil into the engine and burp the cooling circuit. This commercial long block is not engineered for turbocharging kits exceeding 6 PSI, nitrous kits, or demolition derby competition.

• Drain break-in lubricants and install a fresh oil filter after the first 50 miles.
• Change crankcase oil and inspect serpentine belt wear every 3,000 miles of driving.
• Flush radiator fluid and inspect heater hoses every 12 months for steady cooling.

Factory Warranty Crate Contents

Backed by a 36-Month / 100,000-Mile commercial limited warranty on all remanufactured parts and machining. Physical crate contents include the complete remanufactured long block, oil pan, front timing cover, balance shaft assembly, balance certification sheet, and a startup guide.
