VEGE Remanufactured DDH8 5.7L 345ci Premium Grade Long Block Engine

Description

Solve chronic valvetrain fatigue with the VEGE DDH8 Premium Grade Long Block Engine. This 5.7L 345ci V8 power plant yields 345HP for demanding commercial long block repower assignments. Mechanics must verify Multi-Displacement System solenoid harness connectors before securing the intake manifold because plug pinouts differ across truck chassis model years.

Solid ASTM A48 Class 35 gray iron forms the deep crankcase of this VEGE engine core. A nodular iron micro-polished crankshaft spins inside cross-bolted main bearing caps to withstand continuous highway hauling stresses. Cranking requires 185A across 12V starter circuits. Total dry weight 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 DDH8

Transit companies buy VEGE DDH8 Premium Grade 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 DDH8 long block engine 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 DDH8 commercial core to verify durability. Dyno readouts record 345 continuous BHP and 375 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 or mechanical linkages move 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 Terms Crate Contents
