VEGE Remanufactured DCM3 5.7L 350ci Elite Series Long Block Engine

Description

Stop recurring fleet powertrain failure with the VEGE DCM3 Long Block Engine, engineered for commercial long block repower projects in demanding delivery trucks. This 5.7L 350 cid small block V8 produces 255HP at 4,600 RPM. Technicians must check intake manifold bolt angle alignment because 1996 and newer Vortec cylinder heads require vertical intake fasteners.

Solid ASTM A48 Class 35 cast iron forms the 4-bolt main engine casting. A precision ground nodular iron crankshaft pairs with powdered metal connecting rods inside this VEGE engine core. Starter draw measures 165A on standard 12V shop circuits. Dry weight scales at 475 lbs with dimensions measuring 28in length by 25in width by 27in height. Sump holds 5.0 quarts.

Key Features of VEGE DCM3

Municipal repair shops buy VEGE DCM3 Long Block Engine packages to avoid machine shop queues during an industrial engine rebuild turnaround. Remanufacturing operations install new lifters and valve guides to ensure true valve seating across thousands of operating hours.

• Vortec style cast iron cylinder heads optimize fuel atomization through high velocity intake ports.
• A steel hydraulic roller camshaft provides durable valve operation without periodic lash adjustments.
• Hypereutectic pistons resist ring land deformation under sustained heavy payload pulling cycles.
• The DCM3 commercial core holds 0.0016in connecting rod bearing clearance for dependable oil films.
• A heavy duty single roller timing chain prevents camshaft timing drift over extended service life.
• Four bolt main bearing caps lock the rotating crankshaft into the rigid bottom end cradle.
• Multi layer steel head gaskets clamp down to eliminate combustion bore leakage.

Dynamometer Bench Parameters Pressure Benchmarks

Dynamometer runs record 255HP at 4,600 RPM alongside 330 ft-lbs torque at 2,800 RPM for this DCM3 long block engine. Pressure sensors track 55 PSI oil gallery pressure at 2,000 RPM while maintaining 195°F coolant operating temperature. Combustion chamber compression balances at 180 PSI across all eight cylinders within 4% variance. Crankshaft dial indicators confirm 0.0002in TIR total runout. Exhaust manifold pyrometers measure 1,240°F under steady brake load testing.

Field Usability Scheduled Maintenance Directives

Mechanical throttle cable connections require 4 lbs pull force across the bellcrank pivot travel. Fleet mechanics must avoid this commercial replacement engine for conversions lacking factory electronic transmission controllers or vehicles with undersized single core radiators.

• Evacuate initial run break in oil after 500 miles or 30 fleet hours then refill with 5W-30 motor oil.
• Inspect central sequential fuel injection spider poppet valves for leakage before intake installation.
• Check cylinder head bolts in three progressive stages reaching 65 ft-lbs final torque spec.

Crate Manifest Verified Warranty Protection

Backed by the VEGE build standard, this package includes a 3-Year or 100,000-mile limited replacement warranty. The wooden shipping container holds the remanufactured long block core, oil pan, timing cover, valve covers, oil pump pickup tube, plus certified factory inspection test sheets.
