VEGE DD31 5.2L 318ci Car Truck Long Block Remanufactured Crate Engine

Description

High nickel cast iron metallurgy reinforces the VEGE DD31 Remanufactured Crate Engine car truck long block package. Displacement measures 318 cubic inches across a 5.2L Magnum V8 architecture. This remanufactured package produces 230 brake horsepower at 4,400 RPM plus 300 lb-ft torque at 3,200 RPM on pump gas. Cast iron endures loads.

High-nickel cast iron forms the deep-skirt engine block casting with two-bolt cast iron main caps securing the crank train. The rotating group features a nodular cast iron crankshaft linked to forged steel connecting rods. Hypereutectic aluminum dished pistons travel through 3.910-inch cylinder bores stroked across 3.312 inches. Static compression ratio checks out at 9.1:1. Sump capacity measures 5.0 quarts in a stamped steel oil pan while total dry weight registers at 540 lbs.

Key Features of VEGE DD31

Independent repair shops buy VEGE DD31 crate engine units to repower Dodge Ram 1500, Dakota, and Durango sport utility vehicles. Precision machining restores factory clearances to maintain high tractive force on cross-country road trips.

• 3.910-inch bore cylinders undergo diamond plateau honing to seat piston rings without crankcase blowby.
• 1.920-inch intake valves maximize low-speed intake runner airflow for high off-idle torque.
• 1.625-inch exhaust valves evacuate hot combustion gases through cast iron exhaust runners.
• 0.432-inch camshaft valve lift sustains flat torque curves across normal cruising speeds.
• Double roller timing chains prevent cam timing wander under sudden vehicle load shifts.
• Cast iron harmonic balancers dampen crankshaft harmonics during extended engine idling periods.
• Hydraulic roller lifters eliminate valvetrain drag to enhance VEGE DD31 truck motor lifespan.
• 64cc combustion chambers optimize combustion flame travel to suppress detonation under loads.

Combustion Profile Magnum Dyno Parameters

Operating across an effective power band of 1,200 to 5,000 RPM, this V8 engine outputs 230 brake horsepower at 4,400 RPM and 300 lb-ft torque at 3,200 RPM. Camshaft specifications post 196 degrees intake and 204 degrees exhaust duration measured at 0.050-inch lift, along with 0.432-inch intake and 0.432-inch exhaust lift. Combustion stability requires standard 87-octane pump gas. Manifold absolute pressure generates 18 in-Hg idle vacuum at 600 RPM while operating oil pressure stabilizes between 40 to 65 PSI hot.

Chassis Mating Magnum Bay Clearance

The engine features the classic Chrysler LA small-block transmission bellhousing pattern connecting flush to 46RE automatic or NV3500 manual transmissions. Internal neutral balance avoids special externally weighted flywheels. Factory motor mount positions drop straight into Dodge truck chassis without steering linkage contact, providing 3.0 inches of crossmember drop clearance and generous firewall space.

Break In Protocols Fleet Limits

Pre-lube the engine with an external priming tool before initial ignition crank. Circulate high-zinc break-in motor oil and purge cooling passages of air pockets to avoid hot spots. This engine is not engineered for marine saltwater operation, turbocharger boost past 8 PSI, or continuous drag strip transbrake launches.

• Drain initial break-in oil and change filter elements after the first 50 miles.
• Inspect valve adjustment and fluid conditions every 3,000 miles during fleet service.
• Flush radiator coolant and replace accessory drive belts every 12 months of operation.

Factory Warranty Manifest Itemization Details

Each unit includes a 24-Month / 50,000-Mile factory limited warranty covering personal and commercial truck use. The reinforced heavy wooden shipping container holds the remanufactured long block, oil pan, valve covers, front timing cover, oil pump, dyno test documentation, and a technical installation instruction guide.
