VEGE Remanufactured DCA3 5.7L 350ci Premium Grade Long Block Engine

Description

Lower intake manifold gasket erosion and distributor drive gear tooth cupping cause misfires in commercial work trucks and shuttle vans. The VEGE Remanufactured DCA3 Long Block Engine eliminates recurring fluid contamination through an industrial engine rebuild specification. This 5.7L 350ci 8-Cylinder powerplant yields 255HP. Mechanics must verify distributor drive gear mesh backlash prior to locking down the hold-down clamp.

ASTM A48 Class 30 gray iron forms the high strength four bolt main engine block casting. This VEGE engine core utilizes a nodular iron crankshaft, drop forged steel connecting rods, and hypereutectic aluminum pistons. Cranking circuits pull 165A on standard 12V starter motors. Engine dry weight measures 440 lbs with exterior boundaries of 28in length, 26in width, 27in height, holding a 5.0 quarts oil capacity pan.

Key Features of VEGE DCA3

Fleet operators buy VEGE DCA3 Long Block Engine inventory to restore reliable torque in heavy commercial transport trucks. Precision align honing across all five main bearing bulkheads guarantees crankshaft trueness during each commercial long block repower.

• 8-Cylinder iron block features four bolt main caps for bottom end stability under load.
• 16-Valve Vortec cylinder heads feature high velocity kidney shaped combustion chambers.
• 5.7L displacement generates 330 ft-lbs torque for moving heavy service bodies and equipment.
• 0.0014in connecting rod journal clearance maintains uniform hydrodynamic lubrication under continuous towing.
• Hydraulic roller camshaft profiles minimize valvetrain friction and eliminate cam lobe wiping.
• One piece viton rear main seals stop oil seepage past the crank flange.
• DCA3 commercial core assemblies arrive with brand new high pressure oil pump units.
• Multi layer steel head gaskets eliminate coolant leaks across siamesed cylinder decks.

Dynamometer Operating Tolerance Data

Hot cell brake tests establish 255BHP and 330 ft-lbs torque at 4600 RPM on the DCA3 long block engine. Standard diagnostic sensors verify 50 PSI oil gallery pressure at 195°F oil bath operating temperature under load. Cylinder compression gauges record 180 PSI across all eight bores with variance confined under 3% between cylinder banks. Pyrometer probes indicate 1180°F peak exhaust temperature under dyno brake loads. Precision bench dial indicators confirm crankshaft thrust runout remains below 0.0003in TIR across finished bearing surfaces.

Field Service Installation Parameters

Throttle cable linkage return springs demand 5 lbs manual pull effort to actuate the throttle body shaft during pedal travel. This engine is not built for marine outboard hulls, high revving circle track cars, or modern direct injection platforms.

• Drain initial break-in petroleum motor oil at 500 miles and replenish the crankcase with SAE 10W-30 mineral oil.
• Hydraulic roller lifters establish zero lash plus one half turn preload through torqued rocker arm nuts.
• Cast iron cylinder head fasteners require clean oiled threads and strict angle torque execution on assembly.

Warranty Protection Shipment Manifest

Commercial repowers receive protection under the VEGE assembly standard 3-Year 100,000-mile commercial warranty. Each shipping crate encloses the complete assembled remanufactured long block, front timing cover, stamped steel oil pan, stamped valve covers, oil pump pickup screen, and signed dyno performance test sheets.
