VEGE Remanufactured VFCN 6.8L 415ci High Performance Long Block Engine

Description

Variable cam phaser vane oscillation and oil cooler housing gasket extrusion end upon installing the VEGE Remanufactured VFCN 6.8L Long Block Engine. Generating 362HP from a 415ci 10-Cylinder commercial long block repower format, this unit powers severe commercial chassis cabs. Installers must inspect oil cooler housing O-ring compression crush before torquing the oil filter adapter bracket bolts.

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 640 lbs inside a 31in length, 28in width, 30in height mounting stance holding 7.0 quarts oil.

Key Features of VEGE VFCN

Municipal utility fleets buy VEGE VFCN 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.
• Upgraded 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 55 PSI steady pressure to protect high-RPM camshaft journals.
• VFCN 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 362 continuous BHP and 457 ft-lbs torque output at 3250 RPM continuous test load. Pressure gauges register 55 PSI oil gallery pressure at 195°F oil sump temperature, while exhaust gas temp levels off at 1240°F during dyno load. Compression testing demonstrates 180 PSI per cylinder with under 4% variance across all 10 cylinders. Crankshaft center runout measures 0.0003in TIR on the VFCN 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 Crate Manifest Contents

Manufacturing adheres strictly to VEGE assembly standard metrics backed by a 3-Year 100,000-mile fleet warranty. The banded transport pallet holds the assembled long block, steel oil pan, aluminum timing cover, composite valve covers, oil pickup screen, and verified dyno run card.
