VEGE Remanufactured DDA6 3.5L 215ci Multi Purpose Long Block Engine

Description

Rocker shaft retaining bolt fractures and hydraulic timing belt tensioner bleed down cause catastrophic valve strike in commercial fleet sedans. The VEGE Remanufactured DDA6 Long Block Engine eliminates valvetrain collapse through an industrial engine rebuild protocol. This 3.5L 215ci 6-Cylinder powerplant yields 250HP. Mechanics must verify camshaft timing sprocket alignment notches against the rear belt cover before tensioner pin extraction.

Die-cast ASTM A356-T6 aluminum alloy forms the rigid 60-degree V6 block featuring cast iron cylinder liners. The VEGE engine core incorporates a micro polished forged steel crankshaft, forged connecting rods, and graphite coated hypereutectic pistons. Starting demand pulls 155A on standard 12V starters. Assembled dry weight measures 370 lbs with exterior boundaries of 25in length, 24in width, 26in height alongside a 5.5 quarts oil pan.

Key Features of VEGE DDA6

Fleet operators buy VEGE DDA6 Long Block Engine units to maintain dependable executive transport and shuttle schedules. Precision CNC surface milling restores combustion deck planes to ensure airtight head gasket retention during each commercial long block repower.

• 6-Cylinder aluminum block features centrifugally spun iron liners for wear resistance under heavy duty cycles.
• 24-Valve single overhead cam cylinder heads feature induction hardened intake and exhaust valve seats.
• 3.5L displacement produces 250 ft-lbs torque across steady municipal and highway speed bands.
• 0.0013in rod journal clearance provides stable hydrodynamic oil wedges under sustained high RPM operation.
• Upgraded rocker arm shaft pedestals utilize high tensile bolts to prevent valvetrain shear failure.
• Hydraulic timing belt tensioners feature revised seals to prevent piston leak down and valve collision.
• DDA6 commercial core assemblies arrive with brand new high pressure oil pump units.

Dynamometer Test Room Benchmarks

Hot cell brake tests establish 250BHP and 250 ft-lbs torque at 6400 RPM on the DDA6 long block engine. Integrated pressure sensors verify 48 PSI oil gallery delivery at 195°F oil bath operating temperature under full continuous load. Cylinder compression gauges record 180 PSI across all six bores with variance confined under 3% between cylinder banks. Pyrometer probes indicate 1160°F peak exhaust temperature under dyno brake loads. Precision bench dial indicators confirm crankshaft thrust runout remains below 0.0003in TIR across finished surfaces.

Chassis Clearance Installation Guidelines

Mechanical throttle cable linkages demand 4 lbs manual pull effort to actuate the throttle body mechanism during pedal travel. This engine is not built for rear drive solid axle trucks, twin turbo track cars, or stationary agricultural pump skids.

• Drain initial break-in petroleum motor oil at 500 miles and replenish the crankcase with API approved 10W-30 mineral oil.
• Hydraulic lash adjusters located inside rocker arms establish automatic zero lash without manual adjustment shims.
• Torque-to-yield cylinder head fasteners require clean oiled threads and strict angle torque execution on assembly.

Standard Warranty Shipping Manifest

Commercial vehicle investments receive coverage under the VEGE assembly standard 3-Year 100,000-mile warranty policy. The heavy timber transport crate houses the complete assembled remanufactured long block, front timing cover, cast aluminum oil pan, stamped valve covers, oil pump pickup screen, and signed dyno performance test sheets.
