VEGE Remanufactured DDM1 6.1L 370ci High Performance Long Block Engine

Description

High-rpm valve spring seat surge and timing chain guide fracture sideline pursuit vehicles during emergency highway maneuvers. The VEGE Remanufactured DDM1 6.1L 370ci High Performance Long Block Engine eliminates valvetrain instability through a commercial long block repower. This 6.1L 8-Cylinder Hemi build produces 425HP, but mechanics must verify oil pump pickup O-ring seating to prevent air aeration.

Cast from ASTM A48 Class 35 heavy iron with orange-painted crankcases, this VEGE engine core houses high-flow aluminum heads and a forged steel crankshaft. Cold starter draw pulls 175A at 12V. Bare engine weight reaches 485 lbs inside 28in length, 27in width, 28in height dimensions with 7.0 quarts oil capacity.

Key Features of VEGE DDM1

Pursuit mechanics buy VEGE Remanufactured DDM1 6.1L 370ci High Performance Long Block Engine units to restore reliable pursuit acceleration without electronics adaptations. Non-MDS lifters and premium beehive valve springs eliminate high-rpm valvetrain harmonics to sustain wide-open throttle acceleration without lifter needle failure.

• Displacement measures 370ci utilizing a 4.055in bore and 3.580in stroke forged rotating group.
• Non-MDS solid-body hydraulic roller lifters eliminate cylinder deactivation collapse failures permanently.
• High-flow hemispherical aluminum cylinder heads maximize chamber breathing past 6000 RPM.
• AISI 4140 forged steel crankshaft withstands extreme rotational acceleration without deflection.
• DDM1 commercial core line-boring guarantees true crankshaft journal rotation under heavy loads.
• Heavy-duty timing chain dampeners prevent chain whip during sudden deceleration events.
• Multi-layer steel head gaskets lock high combustion pressures inside cylinder bores under load.

Bench Dynamometer Load Statistics

Dyno validation confirms mechanical parameters on each DDM1 long block engine before shipping. The SRT Hemi produces 425HP at 6200 RPM and 420 ft-lbs torque at 4800 RPM. Oil gallery pressure maintains 58 PSI hot at 200°F oil temperature. Cylinder compression balances out at 195 PSI across all cylinders with 3% variance. Crank runout limits to 0.0002in TIR. Exhaust gas temp tops out at 1330°F under full load.

Chassis Installation Service Tasks

Electronic throttle pedal pull resistance checks out at 4 lbs force. This high-output Hemi V8 is NOT suited for vehicles requiring Multi-Displacement System fuel economy computers, low-octane 87 fuel, or trucks with restrictive low-clearance steering shaft columns.

• Perform break-in oil and filter changes following the initial 500 miles of highway driving.
• Inspect timing chain cover front seal and oil pump pickup tube O-ring after initial dyno break-in.
• Verify cylinder head bolt torque down to factory angle-yield specifications following break-in cycles.

Factory Guarantee Crate Inclusions

Built under strict VEGE assembly standard protocols, this remanufactured powertrain includes a 3-Year 100,000-mile commercial warranty. Uncrating reveals the remanufactured long block core, oil pan, timing cover, valve covers, oil pump pickup screen, and certified test sheet.
