VEGE DDM5 5.7L 345ci High Output Long Block Remanufactured Crate Engine

Description

Haul heavy enclosed car trailers using the VEGE DDM5 Remanufactured Crate Engine high output 5.7L 345ci long block package. Produces 400 horsepower at 5,800 RPM and 415 lb-ft torque at 4,200 RPM through hemispherical combustion chambers. Precision torque plate boring and deck resurfacing eliminate bore distortion, restoring high cylinder pressure and rapid highway acceleration on pump gasoline.

Cast iron deep-skirt block casting features cross-bolted four-bolt main bearing caps to withstand high rotational stresses under hard acceleration. The rotating group pairs an induction-hardened nodular iron crankshaft with forged powder metal connecting rods and coated hypereutectic pistons. Cylinder dimensions feature a 3.92-inch bore, a 3.58-inch stroke, and a 10.5:1 compression ratio. A 7-quart stamped steel oil pan holds dry engine weight at 508 lbs.

Key Features of VEGE DDM5

Performance enthusiasts and truck owners buy VEGE DDM5 crate engine units to revitalize high-output pickups and performance sport utility vehicles. This remanufactured long block package reinstates factory horsepower and tire-spinning acceleration without costly chassis modifications.

• 3.92-inch honed cylinder walls seat plasma-molybdenum rings to maintain tight compression under acceleration.
• Aggressive hydraulic roller camshaft profiles optimize high-RPM airflow to produce 400 brake horsepower.
• 2.05-inch intake valves maximize cylinder charge volume for instantaneous throttle acceleration.
• 10.5:1 compression hemispherical combustion chambers burn 89 or 91 octane fuel with complete efficiency.
• 7-quart deep sump steel oil pans maintain constant oil pickup immersion during hard launches.
• High-strength timing chain sets preserve camshaft synchronization and prevent chain stretching.
• Remanufactured twin-plug aluminum cylinder heads receive precision multi-angle valve seat machining.
• The DDM5 replacement engine package includes micro-finished crank journals to prolong rod bearing life.

Combustion Profile Dynamic Power Output

Engineered for high-output power delivery, this 5.7-liter V8 operates with high efficiency across an operational band between 1,800 and 6,000 RPM. Peak output reaches 400 brake horsepower at 5,800 RPM alongside 415 lb-ft torque at 4,200 RPM on premium 91-octane pump gasoline. Camshaft specifications provide 208 degrees duration at 0.050-inch lift, pulling 17 in-Hg manifold vacuum at 680 RPM hot idle. High-volume gerotor oil pumps maintain 48 to 72 PSI oil pressure to safeguard crankshaft bearings under high rotational speeds.

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

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 high output 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 high output 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.
