VEGE Remanufactured VF39 5.8L 351ci High Output Long Block Engine

Description

Eradicate recurring rear main seal leaks with the VEGE VF39 Long Block Engine, built to execute a permanent commercial long block repower on fleet work trucks and heavy delivery vans. This 5.8L 351 cid Windsor High Output V8 delivers 240HP at 4,200 RPM. Installers must check distributor drive gear compatibility because factory steel camshafts require matched steel distributor gears.

Solid ASTM A48 Class 35 cast iron shapes the deep web 90° V8 engine block. A cast nodular iron crankshaft and forged powdered metal rods rotate inside this VEGE engine core. Starter draw measures 170A on 12V vehicle circuits. Dry weight measures 510 lbs across dimensions of 29in length by 25in width by 27in height. Pan capacity holds 5.0 quarts.

Key Features of VEGE VF39

Fleet supervisors buy VEGE VF39 Long Block Engine packages to eliminate recurring downtime during an industrial engine rebuild schedule. Every cylinder head receives hardened valve seat inserts and bronze valve guides to stop valve recession under load.

• Cast iron cylinder heads optimize high velocity intake air swirl for prompt throttle response.
• A performance hydraulic roller camshaft grind produces broad power bands without requiring manual lash adjustments.
• Hypereutectic pistons resist thermal expansion to stop cylinder wall scuffing under heavy towing loads.
• The VF39 commercial core maintains 0.0016in rod bearing oil clearances under heavy dynamometer loads.
• A heavy duty timing chain prevents chain whip and timing retard under sudden acceleration.
• Deep main bearing webs provide bottom end structural rigidity against extreme rotational torque.
• Multi layer steel head gaskets clamp down tightly to eliminate combustion bore leakage.

Dynamometer Bench Validation Load Ratings

Dyno bench certification confirms 240HP at 4,200 RPM and 340 ft-lbs torque at 3,200 RPM for this VF39 long block engine. Gauge monitors record 50 PSI oil gallery pressure at 2,000 RPM with oil temperatures stabilizing at 190°F. Cylinder compression checks record 180 PSI across all eight cylinders within 3% balance. Crankshaft runout checks show 0.0003in TIR total runout. Exhaust temperature probes report 1,220°F under peak load.

Installation Protocols Maintenance Schedule Directives

Manual throttle cable linkages require 4 lbs pull force to sweep from idle stop to wide open throttle. Installers must avoid this heavy duty replacement engine for passenger car front wheel drive platforms or applications without high volume radiator setups.

• Drain break in oil after 500 miles or 30 operating hours then fill with 10W-30 mineral oil.
• Inspect distributor gear mesh and oil pump driveshaft hex engagement before final drop in.
• Check cylinder head fasteners in proper sequence reaching 100 ft-lbs final setting.

Crate Manifest Warranty Protection Coverage

Backed by the VEGE build standard, this long block includes a 3-Year or 100,000-mile manufacturer warranty. The heavy wooden crate holds the remanufactured long block core, oil pan, timing cover, valve covers, oil pump pickup tube, plus certified dyno test documentation.
