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

Description

Satisfy strict highway vehicle emissions regulations with the VEGE DDM4 Remanufactured Crate Engine multi purpose 5.7L 345ci long block package. Produces 390 horsepower at 5,600 RPM and 407 lb-ft torque at 4,000 RPM through hemispherical combustion chambers. Precision torque plate boring and line honing restore cylinder roundness to eliminate oil burning and overcome compression loss on pump gasoline.

Cast iron deep-skirt block casting features cross-bolted four-bolt main bearing caps to stabilize crankshaft journals under diverse multi-purpose vehicle demands. The rotating group pairs an induction-hardened nodular iron crankshaft with forged powder metal connecting rods and hypereutectic aluminum pistons with anti-friction skirt plating. Cylinder dimensions detail a 3.92-inch bore, a 3.58-inch stroke, and a 10.5:1 compression ratio. A 7-quart steel oil pan holds dry weight at 505 lbs.

Key Features of VEGE DDM4

Multi-purpose fleet operators and service shops buy VEGE DDM4 crate engine units to repower utility passenger vans, pickups, and work vehicles. This remanufactured long block package drops into factory engine compartments while reinstating factory fuel economy and emissions standards.

• 3.92-inch honed cylinder bores seat plasma-molybdenum rings to halt blowby under load.
• Hydraulic roller camshaft profiles produce high cylinder pressure across mid-range highway passing speeds.
• 2.05-inch intake valves maximize combustion chamber airflow to support 390 horsepower.
• 10.5:1 compression hemispherical combustion chambers burn 87 or 89 octane fuel with high efficiency.
• 7-quart deep sump steel oil pans maintain oil immersion on steep highway grades.
• Heavy duty timing chains maintain exact camshaft synchronization and prevent chain stretch.
• Remanufactured twin-plug aluminum cylinder heads receive multi-angle valve jobs for maximum seal integrity.
• The DDM4 replacement engine package features micro-finished crank journals to prolong main bearing life.

Combustion Profile Dynamic Power Output

Operating across a potent power band between 1,600 and 5,800 RPM, this multi-purpose 5.7-liter V8 produces 390 brake horsepower at 5,600 RPM alongside 407 lb-ft torque at 4,000 RPM on mid-grade 89-octane pump gasoline. Camshaft specifications provide 204 degrees duration at 0.050-inch lift, pulling 17.5 in-Hg manifold vacuum at 650 RPM hot idle. High-pressure gerotor oil pumps maintain 45 to 70 PSI oil pressure to safeguard crankpins and cam lobes under sustained highway towing loads across hot ambient weather.

Chassis Integration Bellhousing Structural Fitment

The rear block casting fits modern truck automatic transmissions without bellhousing adapters. Internal balance specifications match factory flexplates and torque converters. Symmetrical engine block pad bosses bolt straight to heavy-duty chassis mounts, clearing pickup frame crossmembers, four-wheel-drive front differentials, and steering shafts without chassis contact.

Operational Limits Break In Guidelines

Pressure pre-lube the central oil gallery with 5W-20 mineral break-in oil before starting the engine. Verify full cooling system burping to protect twin-plug cylinder heads from hot spots. This multi-purpose remanufactured long block is not engineered for centrifugal supercharger boost over 6 PSI, nitrous kits, or marine salt water applications.

• Drain initial break-in oil and change oil filter element after 500 miles.
• Inspect exhaust manifold bolt torque and verify coolant hoses every 3,000 miles.
• Replace synthetic engine oil and check PCV valve operation every 12 months.

Factory Warranty Crate Shipping Manifest

VEGE covers this multi-purpose crate unit with a 36-Month or 100,000-Mile remanufactured warranty for commercial and consumer highway applications. Physical crate shipments include the complete long block with oil pan, timing cover, complete valvetrain, oil pump, and an individual quality control build sheet.
