VEGE 865 5.7L 5663cc Heavy Duty Long Block Remanufactured Crate Engine

Description

Featuring 5.7-liter displacement block architecture, the VEGE 865 Remanufactured Crate Engine heavy-duty long block package repowers full-size pickups and commercial haulers. Displacing 5.7L across 5663cc in a ninety-degree V8 format, this motor outputs 381 BHP at 5600 RPM and 401 lb-ft torque at 3600 RPM. Engineered for multi-port fuel injection, it restores massive towing power and mechanical durability.

A deep-skirt cast aluminum V8 block casting features iron cylinder sleeves precision bored to 3.70 inches and stroked to 4.02 inches. The rotating group incorporates a balanced forged steel crankshaft, forged connecting rods, and heavy-duty hypereutectic aluminum alloy pistons. Cylinder pressure achieves a 10.2:1 compression ratio for regular fuel operation. A 7.5-quart steel rear-sump oil pan maintains continuous oil pickup. Total dry engine weight registers 495 lbs for planted truck chassis traction.

Key Features of VEGE 865

Commercial fleet managers buy VEGE 865 crate engine packages to recondition heavy towing trucks and utility transport vehicles without dealer markup. Each remanufactured long block receives precision deck surfacing, line-bored main bearing tunnels, and micro-polished crank journals to eliminate oil burning.

• 3.70-inch cylinder bores feature diamond plateau honing to seat piston rings fast.
• Dual VVT-i valvetrain controls thirty-two valves for broad high-RPM breathing.
• 37mm intake valves and 32mm exhaust valves promote efficient cylinder scavenging.
• 52cc combustion chambers eliminate detonation knock when burning standard 87-octane pump gasoline.
• Multi-layer steel head gaskets seal combustion fire rings under extreme towing heat.
• Roller rocker arms with hydraulic lash adjusters inside the VEGE 865 heads maintain quiet valve action.
• Six-bolt cross-bolted main caps anchor the forged crankshaft under high torque pulls.
• Stamped steel rear-sump oil pan clears four-wheel-drive front differentials and steering linkages.

Combustion Dynamics Dyno Output Specs

The power curve delivers relentless torque output between 1,000 and 5,800 RPM. Peak dynamometer output reaches 381 brake horsepower at 5,600 RPM alongside 401 lb-ft torque at 3,600 RPM. Camshaft duration measures 212 degrees on intake and 208 degrees on exhaust at 0.050-inch lift, alongside 0.390-inch valve lift. The motor runs on standard 87-octane regular pump unleaded gasoline. Intake manifold vacuum pulls 20 in-Hg at a smooth 650 RPM idle. Operating oil pressure regulates between 45 and 70 PSI at 2,500 working RPM.

Drivetrain Interface Engine Bay Clearance

The rear bellhousing pattern aligns flush to longitudinal six-speed automatic truck transmissions. An internal neutral balance crank flange connects straight to production torque converter flexplates. Factory cast aluminum engine mount brackets line up with chassis hydraulic isolators, preserving four inches of clearance above the front steering crossmember.

Break-In Protocol Maintenance Parameters

Pre-lube all engine oil passages with a pressurized tank before initial startup to protect journal bearings. Fill the crankcase with SAE 0W-20 mineral break-in oil and bleed trapped air bubbles from heating circuit hoses. This heavy-duty V8 truck motor is not engineered for aftermarket turbocharger conversions exceeding 8 PSI boost, competitive drag racing, or unmetered nitrous oxide injection.

• Run motor at 2,000 RPM for 20 minutes to bed in camshaft lobes.
• Drain initial break-in oil and install a fresh oil filter after the first 500 miles.
• Replace crankcase motor oil and inspect drive belts every 3,000 miles during regular service.

Verified Warranty Physical Crate Manifest

A 36-Month / 100,000-Mile nationwide limited warranty provides long-term mechanical protection against defects. The heavy transport crate contains the remanufactured long block, stamped steel oil pan, aluminum timing cover, harmonic damper, cast aluminum valve covers, oil pressure verification report, and an installation instruction handbook.
