VEGE Remanufactured DDM2 5.7L 345ci Heavy Duty Long Block Engine

Description

Multi-displacement lifter roller needle bearing seizure scores camshaft lobes in commercial haulers during heavy urban transit. The VEGE Remanufactured DDM2 5.7L 345ci Heavy Duty Long Block Engine cures chronic Hemi valvetrain ticking through an industrial engine rebuild. This 5.7L 8-Cylinder build develops 345HP, requiring installers to inspect variable cam timing oil control solenoid screens.

Constructed around an ASTM A48 Class 35 iron block, this VEGE engine core utilizes twin-plug aluminum cylinder heads and a nodular iron crankshaft. Starter draw demands 170A on 12V circuits. Total dry weight measures 485 lbs within 28in length, 27in width, 28in height dimensions requiring 7.0 quarts oil.

Key Features of VEGE DDM2

Service managers buy VEGE Remanufactured DDM2 5.7L 345ci Heavy Duty Long Block Engine packages to keep municipal utility trucks operating without high equipment turnover costs. Upgraded needle roller bearings in MDS lifters resist lubrication starvation to stop premature camshaft lobe flattening under prolonged fleet idle conditions.

• Displacement spans 345ci across a 3.917in bore and 3.578in stroke crankshaft radius.
• Upgraded MDS hydraulic roller lifters prevent needle bearing lockup and camshaft lobe destruction.
• Twin-spark aluminum cylinder heads promote fast flame travel to maximize fuel combustion efficiency.
• Precision plateau-honed cylinder walls establish immediate piston ring seal without blowby.
• DDM2 commercial core line-boring guarantees true crankshaft journal rotation under heavy loads.
• Tri-metal copper-lead bearings absorb abrasive micro-debris to prevent crankshaft journal scoring.
• Reinforced composite timing chain guides eliminate guide slapping under fluctuating oil pressures.

Test Bench Dyno Limits

Hot bench runs measure performance parameters on each DDM2 long block engine before dispatch. The 5.7L Hemi develops 345HP at 5300 RPM alongside 375 ft-lbs torque at 4200 RPM. Sump oil gallery pressure stabilizes at 55 PSI at 195°F operating temperature. Cylinder compression gauges show 185 PSI across all ports with 3% variance. Crankshaft runout checks at 0.0003in TIR. Dynamic exhaust gas temp stabilizes at 1280°F under dyno loading.

Bay Constraints Maintenance Schedules

Electronic throttle pedal pull resistance checks out at 4 lbs force. This 5.7L Hemi V8 build is NOT compatible with non-MDS computer calibrations without tuning modification, pre-2003 vintage Dodge engine bays, or low-grade non-detergent motor oils.

• Flush break-in engine oil and replace the filter element after 500 highway transit miles.
• Inspect variable cam timing solenoid screen and oil pressure control valves after 100 operating hours.
• Check cylinder head bolt torque down to factory angle-yield specifications following initial run cycles.

Commercial Protection Included Hardware

Protected under the dependable VEGE assembly standard, this remanufactured unit features a 3-Year 100,000-mile commercial warranty. The sturdy transport crate contains the long block engine, oil pan, valve covers, timing cover, oil pump with screen, and signed quality inspection sheet.
