VEGE VCM5 5.7L 350ci Premium Grade Long Block Remanufactured Crate Engine

Description

High-tensile gray cast iron reinforces the VEGE VCM5 Remanufactured Crate Engine in 5.7L 350ci premium grade long block trim. This remanufactured small block Chevrolet V8 outputs 250 brake horsepower at 4,400 RPM and 330 lb-ft torque at 2,800 RPM. Built for GM pickups, vans, and SUVs, this unit delivers dependable towing strength without powertrain computer modifications.

Premium cast iron cylinder blocks undergo sonic thickness checking, deck squaring, and plateau cylinder honing to 4.000-inch standard finished bore diameters. A remanufactured nodular cast iron crankshaft spins inside four-bolt cast iron main caps clamped by high-grade bolts. Forged powdered metal connecting rods mate to hypereutectic aluminum pistons with anti-scuff skirt coatings. This engine features a 3.480-inch stroke, 9.4:1 compression ratio, 5.0-quart oil capacity, and weighs 435 lbs dry.

Key Features of VEGE VCM5

Fleet operations buy VEGE VCM5 crate engine packages to rebuild severe-duty commercial haulers, box trucks, and passenger vans. Each long block matches original GM small-block perimeter mounting points and standard commercial drivetrain patterns for fast mechanical exchange.

• 1.94-inch intake and 1.50-inch exhaust stainless steel valves ensure complete cylinder head port seal integrity.
• 64cc cast iron combustion chambers maintain balanced thermal resistance across heavy commercial run cycles.
• 0.414-inch intake lift hydraulic roller camshafts promote extended valvetrain lifespan and low parasitic friction.
• 4.000-inch bore cylinders feature chromium-faced top piston rings to maintain cylinder compression under tow loads.
• Double-roller steel timing sets prevent camshaft timing drift over hundreds of thousands of work hours.
• Ductile iron four-bolt main bearing caps withstand elevated combustion pressures without journal flex.
• VEGE VCM5 platinum components include new brass freeze plugs to resist coolant passage corrosion.
• Rear main one-piece Viton seals prevent crankcase oil leaks during high operating temperatures.

Calibrated Torque Curve Specifications

The hydraulic roller camshaft is ground with 191 degrees intake and 196 degrees exhaust duration measured at 0.050-inch valve lift on a 111-degree center. This profile produces 18 in-Hg intake manifold vacuum at 600 RPM to sustain power brake boosters and vacuum accessories. The small block outputs 330 lb-ft peak torque between 2,400 and 3,600 RPM on standard 87-octane pump gasoline. Calibrated internal oiling galleys maintain 40 to 65 PSI hot oil pressure through a high-volume Melling oil pump.

Chassis Mating Clearance Dimensions

Classic Chevrolet V8 transmission bellhousing patterns mate straight to 4L80E, 4L60E, and manual transmissions without custom adapter hardware. Neutral balance 168-tooth flexplates clear factory starter locations while standard small block block bosses bolt to stock frame pads. Stamped steel rear sump oil pans clear steering gear links and GM truck front crossmembers.

Lubrication Schedule Duty Limits

Mechanics must prime engine oil galleys with an oil pump primer tool before firing spark plugs. Use high-zinc mineral break-in oil during the initial operational run to establish proper bearing run-in. This remanufactured long block is not engineered for centrifugal supercharger boost exceeding 6 PSI, methanol fuel, or unmetered nitrous oxide injection.

• Drain the initial break-in oil and replace spin-on oil filters after the first 500 miles.
• Change crankcase motor oil with approved 10W-30 synthetic blend oil every 3,000 miles.
• Inspect accessory belt tension and cooling system hoses every 12 months in service.

Warranty Terms Manifest Breakdown

VEGE protects this long block with a 36-Month or 100,000-Mile platinum remanufactured warranty package. The secured shipping crate contains the assembled long block, stamped steel valve covers, oil pan, timing cover, water pump gaskets, dynamic balance certification sheets, and installation instruction manuals for fast shop turnaround.
