VEGE DDM8 5.7L 345ci Platinum Grade Long Block Remanufactured Crate Engine

Description

Eliminate severe valve drop mechanical failure with the VEGE DDM8 Remanufactured Crate Engine Platinum Grade 5.7L 345ci long block package. Produces 395 horsepower at 5,600 RPM and 410 lb-ft torque at 4,000 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 506 lbs.

Key Features of VEGE DDM8

Discerning truck owners and technicians buy VEGE DDM8 crate engine units to repower high-trim pickups and sport utility vehicles. This Platinum Grade 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.
• Platinum spec hydraulic roller camshaft profiles optimize high-RPM airflow to produce 395 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 DDM8 replacement engine package includes micro-finished crank journals to prolong rod bearing life.

Combustion Profile Dynamic Power Output

Engineered for premium 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 395 brake horsepower at 5,600 RPM alongside 410 lb-ft torque at 4,000 RPM on premium 91-octane pump gasoline. Camshaft specifications provide 206 degrees duration at 0.050-inch lift, pulling 17.5 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 Platinum Grade 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 Platinum Grade 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.
