VEGE Remanufactured DDM4 5.7L 345ci Multi Purpose Long Block Engine

Description

Prevent persistent crankcase blow-by with the VEGE DDM4 Multi Purpose Long Block Engine. This 5.7L 345ci V8 powerplant produces 340HP for municipal commercial long block repower chassis applications. Fleet technicians must check Multi-Displacement System solenoid oil passages in the valley pan area before final assembly because blocked oil screens cause lifter latching failures.

Solid ASTM A48 Class 35 gray iron lines the deep crankcase of this VEGE remanufactured long block. A micro-polished nodular cast iron crankshaft spins inside cross-bolted main bearing caps to withstand continuous highway hauling stresses. Cranking requires 185A across 12V starter circuits. Total dry mass measures 500 lbs inside an installation envelope of 29in length by 27in width by 28in height holding 7.0 quarts oil.

Key Features of VEGE DDM4

Transit companies buy VEGE DDM4 Multi Purpose Long Block Engine packages to avoid fleet downtime during an industrial engine rebuild. CNC diamond honing creates uniform cylinder wall crosshatching to ensure instant piston ring seal.

• Generous 345ci displacement supplies immense rotational force for utility towing applications.
• Hemispherical combustion chamber heads improve airflow velocity and optimize flame travel.
• Austenitic stainless steel valves maintain seating face integrity past 1,420°F exhaust temperatures.
• Tri-metal copper lead rod bearings support 0.0015in oil clearances under continuous highway load cycles.
• The DDM4 commercial core utilizes a factory profiled roller camshaft for superior low end responsiveness.
• Aluminum alloy hypereutectic pistons control thermal expansion to prevent cold bore scuffing.
• Multi layer steel cylinder head gaskets maintain combustion seals against continuous cylinder pressures.

Dyno Bench Output Standards

Controlled dyno load cycles stress the DDM4 long block engine to verify durability. Dyno readouts record 340 continuous BHP and 370 ft-lbs torque output at 3,200 RPM. Main oil gallery pressure maintains 55 PSI at 190°F operating temperature. Exhaust gas sensors confirm safe 1,360°F heat thresholds. Individual cylinder compression stands at 185 PSI within 3% variance while crank runout checks out at 0.0003in TIR.

Deployment Boundaries Field Upkeep

Drive by wire throttle actuators move smoothly against 4.5 lbs applied tension. Do not install this modern hemispherical head V8 into passenger chassis lacking front frame rail clearance for dual exhaust downpipes.

• Perform fluid and spin-on filter changes at strict 4,000-mile or 140 run hours service marks.
• Inspect hydraulic roller lifter action and pushrods every 40,000 operating miles.
• Check cylinder head bolt torque clamp loads during scheduled major fleet overhauls.

Warranty Coverage Packaged Hardware

Craftsmen build every unit to the verified VEGE assembly standard for total mechanical reliability. Buyers receive 3-Year or 100,000-mile commercial limited powertrain warranty protection. The wood skid holds the assembled long block engine, oil pan, front timing casing, valve covers, oil pickup tube, and signed bench test certificate.
