VEGE Remanufactured VFXJ 6.2L 379ci High Output Long Block Engine

Description

Fatigued valve springs and worn rocker arm roller trunnions cause catastrophic valve drop in heavy commercial haulers. Choosing the VEGE Remanufactured VFXJ High Output Long Block Engine resolves severe valvetrain breakdown during an industrial engine rebuild. This 6.2L 379ci 8-Cylinder SOHC powerplant delivers 385HP. Mechanics must verify camshaft phaser oil control solenoid screen cleanliness before startup.

High strength ASTM A48 Class 35 cast iron forms the deep skirt engine block beneath dual-plug aluminum cylinder heads. A balanced forged steel crankshaft spins on tri-metal copper lead bearings inside this VEGE engine build. Heavy duty 12V starter motors draw 180A during cold winter morning ignition cycles. Total unrigged dry weight reaches 580 lbs across dimensions of 30in length, 28in width, 29in height. The cast aluminum oil sump holds 7.0 quarts.

Key Features of VEGE Remanufactured VFXJ

Fleet directors buy VEGE Remanufactured VFXJ High Output Long Block Engine packages to rebuild heavy utility service trucks. Every commercial long block repower integrates upgraded valve springs and premium rocker assemblies to handle continuous severe towing stress.

• Beehive valve springs prevent high RPM resonance and eliminate catastrophic valve drop failure.
• Single overhead camshafts actuate two spark plugs per cylinder for complete combustion burn efficiency.
• 0.0016in rod journal clearances preserve protective hydrodynamic oil films under sustained grade hauling.
• The VFXJ commercial core features cross bolted main caps for extreme bottom end crankcase rigidity.
• Multi layer steel cylinder head gaskets maintain fire ring seal integrity under elevated combustion heat.
• Plateau honed cylinder walls allow ductile iron rings to seat fast without bore glazing.
• Stellite faced exhaust valves withstand continuous thermal loading without seat recession.

Dynamometer Performance Test Benchmarks

Dynamometer cell testing rates this VFXJ long block engine at 385 BHP and 405 ft-lbs of continuous torque at 4500 RPM. Main oil galleries deliver 55 PSI at 195°F oil pan thermal equilibrium. Exhaust gas thermocouple probes register 1260°F during sustained max load cycles on the water brake absorber unit. Compression testing confirms 195 PSI across all eight cylinders within 3% balance across both cylinder banks. Crankshaft total runout measures under 0.0003in TIR to preserve heavy duty main bearing shells under load.

Commercial Mechanical Chassis Parameters

Drive-by-wire electronic throttle body plugs snap into connector receptacles with zero manual cable adjustment. This large displacement iron block V8 is NOT compatible with light duty passenger sedans, marine inboard pleasure craft, or older carbureted truck manifolds lacking ECU provisions.

• Drain break-in motor lubricant and replace the spin-on filter element at 500 miles or 30 operating hours.
• Hydraulic lash adjusters seat beneath roller rocker arms with zero manual valve lash adjustment steps required.
• Torque cylinder head torque-to-yield fasteners using specified angle rotation increments without subsequent hot retorque passes.

Crated Freight Warranty Terms

Engineered to meet the stringent VEGE assembly standard, this heavy duty unit includes a 3-Year 100,000-mile parts warranty. The timber freight crate encloses the long block, cast aluminum oil pan, front timing cover, composite valve covers, oil pickup screen, and authenticated shop dynamometer test sheet.
