VEGE Remanufactured DFXW 5.4L 330ci Premium Grade Long Block Engine

Description

Cam phaser vane slap and two-piece spark plug separation cease after installing the VEGE Remanufactured DFXW 5.4L Long Block Engine. Generating 300HP from a 330ci 8-Cylinder commercial long block repower format, this unit powers commercial utility fleet trucks. Mechanics must check variable camshaft timing solenoid screen cleanliness before securing front aluminum timing covers.

Constructed from high-tensile ASTM A48 Class 35 gray iron, the engine block resists torsional chassis twist under heavy cargo loads. This VEGE engine core utilizes induction-hardened forged steel crankshaft journals and stellite-faced valves. Cranking starter demand requires 12V 190A. Engine dry weight reaches 530 lbs inside a 28in length, 27in width, 28in height mounting stance holding 7.0 quarts oil.

Key Features of VEGE DFXW

Municipal utility fleets buy VEGE DFXW commercial long block packages to restore long-distance route fleet dependability. Modern clean-room shops enforce verified industrial engine rebuild benchmarks throughout each production cycle.

• Forged micro-alloy steel crankshaft features fillet-radiused journals holding 0.0003in TIR runout limits.
• Revised spark plug port threads feature full thread depth to eliminate cylinder head plug blowouts.
• Multi-layer steel cylinder head gaskets maintain combustion chamber seal integrity under severe thermal cycling.
• Plateau-honed cylinder walls provide optimal oil retention to seat steel compression rings without blowby.
• High-flow rotor oil pump delivers 58 PSI steady pressure to protect high-RPM camshaft journals.
• DFXW commercial core includes revised oil return channels to accelerate crankcase drainback under heavy loads.
• Tri-metal bearings feature copper-lead backing to absorb abrasive debris particles safely under heavy loads.

Dynamometer Load Verification Bench Data

Certified dyno testing confirms 300 continuous BHP and 365 ft-lbs torque output at 3750 RPM continuous test load. Pressure gauges register 58 PSI oil gallery pressure at 195°F oil sump temperature, while exhaust gas temp levels off at 1260°F during dyno load. Compression testing demonstrates 180 PSI per cylinder with under 4% variance across all eight cylinders. Crankshaft center runout measures 0.0003in TIR on the DFXW long block engine.

Installation Requirements Negative Filter Rules

Mechanical throttle lever operation takes 5 lbs pull force through the linkage bracket assembly. This power unit is NOT engineered for passenger vans using electronic fly-by-wire throttle bodies without manual conversion brackets. Shop technicians must carry out standardized maintenance routines on all newly mounted units.

• Empty initial break-in lubricant reservoir at 500 miles or 30 run hours.
• Check hydraulic lash adjuster zero-lash travel limits prior to front timing cover sealing.
• Retorque cylinder head torque-to-yield fasteners in three steps following factory sequence.

Warranty Statement Shipping Pallet Inventory

Manufacturing adheres strictly to VEGE assembly standard metrics backed by a 3-Year 100,000-mile fleet warranty. The timber freight crate houses the long block core, steel oil pan, aluminum timing cover, stamped valve covers, oil pickup tube, and signed dyno verification form.
