VEGE DCX14 5.3L 325ci Premium Grade Long Block Remanufactured Crate Engine

Description

Featuring precision remanufactured cylinder bore geometry, the VEGE DCX14 Remanufactured Crate Engine premium grade long block package restores full GM truck capability. Displacement measures 325 cubic inches across a 5.3L V8 architecture. This remanufactured package produces 315 brake horsepower at 5,200 RPM plus 335 lb-ft torque at 4,000 RPM on standard pump gas.

Deep-skirt cast iron forms the engine block casting with cross-bolted six-bolt main bearing caps stabilizing the crank train. The rotating group features a nodular cast iron crankshaft matched to forged powdered metal I-beam connecting rods. Hypereutectic aluminum flat-top pistons travel through 3.780-inch cylinder bores stroked across 3.622 inches. Static compression ratio checks out at 9.9:1. Sump capacity measures 6.0 quarts in a rear sump oil pan while total dry weight registers at 518 lbs.

Key Features of VEGE DCX14

Truck mechanics buy VEGE DCX14 crate engine units to replace worn Vortec engines in Silverado, Tahoe, and Suburban platforms. CNC blueprint machining restores factory tolerances to maintain trouble-free travel across multi-state routes.

• 3.780-inch bore cylinders undergo torque plate honing to maintain true circular shape under head bolt torque.
• 2.000-inch intake valves maximize cylinder head port velocity to enhance midrange passing torque.
• 1.550-inch exhaust valves evacuate combustion heat through high-flow aluminum exhaust ports.
• 0.479-inch camshaft valve lift sustains flat torque across broad engine operating ranges.
• Hardened silent timing chains prevent camshaft timing shift across prolonged operation.
• Cast nodular iron harmonic balancers suppress crankshaft torsional oscillation under load.
• Non-AFM hydraulic roller lifters eliminate common valvetrain collapse to bolster VEGE DCX14 truck motor endurance.
• 61cc combustion chambers optimize flame speed to suppress spark knock under high summer temperatures.

Combustion Profile Gasoline Dyno Output

Operating across an effective power band of 1,600 to 5,800 RPM, this V8 engine outputs 315 brake horsepower at 5,200 RPM and 335 lb-ft torque at 4,000 RPM. Camshaft specifications post 196 degrees intake and 201 degrees exhaust duration measured at 0.050-inch lift, along with 0.479-inch intake and 0.467-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 Powertrain Bay Envelope

The engine block matches standard GM Gen IV bellhousing patterns connecting flush to 4L60E or 6L80 transmissions. Internal neutral balance avoids special counterweighted flywheels. Factory side motor mount bosses drop straight into Silverado truck frame rails, preserving 3.0 inches of crossmember drop clearance and ample perimeter clearance around steering shafts.

Break In Protocols Duty Thresholds

Pre-lubricate the engine using an oil pressure priming canister before first ignition crank. Circulate high-zinc 5W-30 motor oil and bleed cooling lines to purge air blocks. This engine is not engineered for marine applications, dry sump conversions, or boost levels past 7 PSI on stock ring gaps.

• Change initial break-in engine oil and spin-on filters after the first 50 miles.
• Inspect valvetrain noise and engine fluid levels every 3,000 miles of service.
• Flush radiator coolant passages and inspect accessory pulleys every 12 months.

Factory Warranty Manifest Itemization

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