VEGE DFXF 4.6L 281ci Car Truck Long Block Remanufactured Crate Engine

Description

Eliminate chronic valvetrain failure using the VEGE DFXF Remanufactured Crate Engine 4.6L 281ci car truck long block package. Generating 230 horsepower at 4,750 RPM and 290 lb-ft torque at 3,500 RPM, this modular two-valve V8 delivers dependable performance. Structural block web reinforcement and upgraded internal oil passages withstand the rigorous demands of commercial fleet hauling and sustained highway travel.

A deep-skirt cast iron block casting features cross-bolted six-bolt main bearing journals paired with a balanced nodular cast iron crankshaft. Cracked-powder metal connecting rods hold hypereutectic aluminum pistons within a 3.552-inch bore and 3.543-inch stroke. Compression measures 9.4:1 for regular fuel use. The front-sump stamped steel oil pan holds 6.0 quarts, with dry weight at 505 lbs.

Key Features of VEGE DFXF

Truck owners choose to buy VEGE DFXF crate engine packages to overhaul pickups and sport utility vehicles. Precision remanufactured cylinder heads and balanced rotating components restore smooth idle quality and low-speed torque across demanding vehicle applications.

• Single overhead camshaft heads utilize roller rocker followers to eliminate internal mechanical drag.
• 44.5 mm intake valves deliver dense air charges into high-swirl combustion chambers.
• DFXF car truck engines receive precision plateau cylinder honing for immediate ring seating.
• Computerized dynamic balancing limits rotational vibration across the entire engine speed band.
• Multi-layer steel cylinder head gaskets provide positive combustion containment under thermal stress.
• Line-bored cam towers reestablish tight hydrodynamic oil wedge films during hot idle periods.
• Pre-hung timing components maintain precise camshaft phasing without premature wear.

Combustion Chamber Dyno Characteristics

Operating across an engine band from 1,200 to 5,200 RPM, this V8 creates 230 peak brake horsepower at 4,750 RPM alongside 290 lb-ft torque at 3,500 RPM. Camshaft duration checks in at 194 degrees intake at 0.050-inch lift, with 0.480-inch valve lift. Standard 87-octane pump gasoline provides knock-free operation. Warm idle vacuum pulls 20 in-Hg at 600 RPM, with oil pressure steady between 45 to 70 PSI hot.

Chassis Clearance Transaxle Integration

The rear engine flange matches modular Ford transmission bolt patterns for 4R70W and 4R75W automatic transmissions. Neutral internal balancing simplifies flexplate alignment. Oil pan contours clear vehicle crossmembers and steering linkages, providing ample space around steering shafts, exhaust downpipes, and firewall clearance points.

Maintenance Protocols Operating Boundaries

Lubricate all internal journals using a pressure priming tank prior to initial ignition cycles. Fill the crankcase with 5W-20 synthetic blend oil and eliminate all air bubbles from the radiator. This remanufactured long block is not engineered for centrifugal blowers running over 7 PSI or unmetered nitrous systems.

• Change out initial break-in motor oil and install a new filter after the first 50 miles.
• Renew engine oil and conduct multi-point visual inspections every 3,000 miles of service.
• Drain and refill cooling system fluid every 12 months to stop internal corrosion.

Factory Warranty Crate Contents

Protected by a 36-Month / 100,000-Mile commercial-grade limited warranty against structural defects. The wooden crate contains the remanufactured long block, oil pan, front timing cover, reconditioned cylinder heads, balance inspection paperwork, and an engine installation manual.
