VEGE DFDN 5.4L 330ci Elite Series Long Block Remanufactured Crate Engine

Description

Need dependable replacement commercial truck power? Select the VEGE DFDN Remanufactured Crate Engine 5.4L 330ci elite series long block package. Producing 260 horsepower at 4,500 RPM and 350 lb-ft torque at 2,500 RPM, this modular V8 provides enormous pulling power. Reconditioned two-valve cylinder heads and renewed rotating components restore factory payload capability to commercial fleet haulers and service vans.

A deep-skirt cast iron engine block incorporates cross-bolted six-bolt main bearing caps supporting a heavy-duty balanced nodular iron crankshaft. Forged powder-metal connecting rods secure hypereutectic aluminum pistons running a 3.552-inch bore and 4.165-inch stroke. Compression registers 9.0:1 for detonation prevention. The stamped steel rear-sump pan holds 6.0 quarts of oil, bringing dry weight to 535 lbs.

Key Features of VEGE DFDN

Fleet maintenance teams buy VEGE DFDN crate engine assemblies to overhaul heavy-duty F-250 and E-350 vehicles. Strict dimensional blueprinting eliminates chronic oil consumption and timing chain slap, keeping vital utility vehicles on the road without breakdown disruptions.

• Single overhead camshaft heads utilize roller rocker followers to reduce internal engine friction.
• 44.5 mm intake valves deliver dense air charges into cylinders for massive low-end pulling power.
• DFDN elite series packages incorporate fully threaded spark plug bores to eliminate thread failure.
• Cross-bolted main caps anchor the rotating group securely under severe continuous towing loads.
• Multi-layer steel head gaskets seal high cylinder combustion pressures across both banks.
• Line-honed camshaft journals maintain uniform oil pressure under heavy summer pulling heat.
• Pre-timed dual timing chains maintain exact synchronization under rapid engine deceleration.

Combustion Chamber Dyno Characteristics

Operating across an engine band from 1,000 to 5,000 RPM, this V8 outputs 260 peak brake horsepower at 4,500 RPM and 350 lb-ft torque at 2,500 RPM. Camshaft duration measures 194 degrees intake at 0.050-inch lift, with 0.480-inch total valve lift. Designed to run on 87-octane regular pump gasoline. Warm idle vacuum pulls 19 in-Hg at 600 RPM, while oil pressure reads 45 to 70 PSI hot.

Chassis Clearance Transaxle Integration

The bellhousing flange bolts directly to modular Ford 4R100 and 4R70W automatic transmissions without custom adapters. Zero-balance internal design permits use of standard flexplates and front harmonic dampers. The rear-sump pan clears heavy truck front twin I-beam crossmembers, providing ample clearance for brake booster lines and exhaust downpipes.

Maintenance Protocols Operating Boundaries

Pre-lube the engine with an external oil tank before starting to protect overhead cam bearing surfaces. Charge the crankcase with 5W-20 synthetic blend oil and bleed the cooling circuit. This engine unit is not engineered for superchargers generating over 6 PSI or continuous high-RPM marine endurance racing.

• Drain break-in motor oil and spin on a fresh filter after the first 50 miles.
• Change the crankcase oil and inspect serpentine drive belts every 3,000 miles of operation.
• Flush engine coolant and inspect radiator cap pressure every 12 months without fail.

Factory Warranty Crate Contents

Includes a 36-Month / 100,000-Mile commercial limited warranty against remanufacturing defects. The secure crate contains the remanufactured long block, complete oil pan, timing covers, reconditioned heads, oil pump assembly, balance documentation sheet, and a comprehensive installation instruction guide.
