VEGE Remanufactured DFF6 4.6L 281ci Platinum Grade Long Block Engine

Description

Plastic timing chain guide disintegration and variable phaser chatter ruin late-model work trucks during heavy towing. The VEGE Remanufactured DFF6 4.6L 281ci Platinum Grade Long Block Engine eliminates modular valvetrain failure through an industrial engine rebuild. This 4.6L 8-Cylinder 3-valve build delivers 292HP, requiring installers to ensure absolute cleanliness of variable cam timing control solenoids.

Constructed with an ASTM A48 Class 30 gray iron block, this VEGE engine core houses 3-valve aluminum cylinder heads and a micro-polished forged steel crank. Starter draw requires 160A on 12V circuits. Total dry weight measures 490 lbs within 28in length, 28in width, 28in height dimensions requiring 6.0 quarts oil.

Key Features of VEGE DFF6

Fleet supervisors buy VEGE Remanufactured DFF6 4.6L 281ci Platinum Grade Long Block Engine units to restore reliable service in commercial utility pickups without purchasing expensive new chassis. Reinforced cast iron timing tensioners replace plastic OEM tensioners to maintain stable oil pressure to the overhead cam phasers.

• Displacement spans 281ci utilizing a 3.552in bore and 3.543in stroke rotating assembly.
• Heavy-duty cast iron timing tensioners eliminate oil pressure bleed-down and chain slap.
• Updated variable cam timing phasers resist internal rotor pin shear during rapid load transitions.
• Three-valve aluminum cylinder heads maximize chamber airflow for strong high-rpm cargo pulling.
• DFF6 commercial core machining ensures cylinder wall roundness within 0.0002in across each bore.
• Hydraulic roller finger followers feature micro-roller bearings to minimize camshaft friction.
• Multi-layer steel head gaskets lock high combustion pressures inside cylinder bores under load.

Dyno Test Cell Metrics

Hot bench runs measure performance parameters on each DFF6 long block engine before dispatch. The engine develops 292HP at 5700 RPM alongside 320 ft-lbs torque at 4000 RPM. Sump oil gallery pressure stabilizes at 55 PSI at 195°F operating temperature. Cylinder compression gauges show 180 PSI across all ports with 3% variance. Crankshaft runout checks at 0.0002in TIR. Dynamic exhaust gas temp stabilizes at 1260°F under dyno loading.

Bay Envelope Service Tasks

Electronic throttle pedal pull resistance checks out at 4 lbs force. This 3-valve modular V8 is NOT compatible with early 2-valve computer wiring harnesses, front-wheel-drive passenger car chassis, or vehicles running non-synthetic engine oils.

• Perform break-in oil and filter changes following the initial 500 miles of highway driving.
• Inspect variable cam timing oil control solenoids and screens after the first 100 operating hours.
• Check cam cover perimeter fastener torque to 89 in-lbs following initial temperature cycles.

Commercial Warranty Freight Contents

Protected under the dependable VEGE assembly standard, this remanufactured unit features a 3-Year 100,000-mile commercial warranty. The sturdy transport crate contains the long block engine, oil pan, valve covers, timing cover, oil pump with screen, and signed quality inspection sheet.
