VEGE DC03 5.7L 350ci Heavy Duty Long Block Remanufactured Crate Engine

Description

Halt chronic rear main seal weeping with the VEGE DC03 Remanufactured Crate Engine heavy-duty long block package. Displacing 5.7L across 350ci in a ninety-degree V8 format, this motor outputs 210 BHP at 4000 RPM and 300 lb-ft torque at 2800 RPM. Engineered for throttle-body or carbureted fuel induction, it repowers work trucks and commercial haulers with unyielding pulling power.

A heavy-duty four-bolt main cast iron V8 block houses cylinder bores precision bored to 4.00 inches with a 3.48-inch stroke. The reciprocating group combines a nodular iron crankshaft, drop-forged steel connecting rods, and heavy-duty hypereutectic aluminum pistons. Cylinder pressure achieves an 8.5:1 compression ratio for regular fuel operation. A 5.0-quart steel rear-sump oil pan maintains continuous oil pickup during steep grade climbs. Total dressed dry weight registers 450 lbs for solid truck traction.

Key Features of VEGE DC03

Commercial fleet managers buy VEGE DC03 crate engine packages to recondition medium-duty haulers and work trucks without dealership markup. Each remanufactured long block receives precision deck squaring, line-honed main bearing tunnels, and micro-polished crank journals to eliminate oil burning under continuous heavy loads.

• 4.00-inch cylinder bores feature diamond plateau honing to seat piston rings fast.
• Overhead valve pushrod valvetrain provides sixteen valves of high-volume air charge.
• 49.3mm intake valves and 38mm exhaust valves promote smooth combustion chamber scavenging.
• 64cc combustion chambers eliminate detonation knock when burning standard 87-octane pump gasoline.
• Reinforced multi-layer steel head gaskets seal combustion fire rings under heavy towing loads.
• Hydraulic flat tappet lifters inside the VEGE DC03 block maintain quiet valve actuation.
• Four-bolt main caps anchor the nodular iron crankshaft under sustained 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 robust pulling power between 800 and 4,400 RPM. Peak dynamometer output reaches 210 brake horsepower at 4,000 RPM alongside 300 lb-ft torque at 2,800 RPM. Camshaft duration measures 202 degrees on intake and 206 degrees on exhaust at 0.050-inch lift, alongside 0.410-inch valve lift. The motor runs on standard 87-octane regular pump unleaded gasoline. Intake manifold vacuum pulls 19.5 in-Hg at a smooth 650 RPM idle. Operating oil pressure regulates between 40 and 65 PSI at 2,200 working RPM.

Drivetrain Interface Engine Bay Clearance

The rear bellhousing pattern aligns flush to longitudinal manual and automatic truck transmissions. An internal neutral balance crank flange connects straight to production flywheels or torque converter flexplates. Factory cast iron engine mount brackets line up with chassis rubber 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 and lifters. Fill the crankcase with SAE 10W-30 high-zinc mineral break-in oil and bleed trapped air bubbles from heating circuit hoses. This heavy-duty small block motor is not engineered for turbocharging exceeding 7 PSI boost, competitive mud racing, or unmetered nitrous oxide injection.

• Run motor at 2,000 RPM for 20 minutes to bed in flat tappet 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, stamped valve covers, oil pressure verification report, and an installation instruction handbook.
