VEGE DFY5 5.4L 330ci High Output Long Block Remanufactured Crate Engine

Description

Restore factory sports truck acceleration using the VEGE DFY5 Remanufactured Crate Engine 5.4L 330ci high output long block. Generating 300 horsepower at 5,000 RPM and 365 lb-ft torque at 3,750 RPM, this three-valve V8 restores heavy hauling performance. Variable camshaft timing phasers interface with computer controls to optimize low-end towing grunt and high-RPM highway passing muscle.

Deep-skirt cast iron block construction houses cross-bolted six-bolt main bearing journals paired with a balanced nodular iron crankshaft. Cracked powdered-metal connecting rods secure coated hypereutectic pistons across a 3.552-inch bore and 4.165-inch stroke. Compression ratio measures 9.8:1 for crisp efficiency. A heavy-gauge steel rear-sump pan holds 7.0 quarts of oil, with total dry weight at 540 lbs.

Key Features of VEGE DFY5

Fleet operators buy VEGE DFY5 crate engine units to resolve three-valve valvetrain wear and cam phaser chatter in late-model trucks. Premium remanufactured long blocks deliver updated internal oiling restrictors to guarantee consistent lubrication across upper cylinder heads.

• Three-valve cylinder heads incorporate dual intake valves to dramatically increase cylinder filling efficiency.
• Variable camshaft timing phasers adjust camshaft timing for wide-spectrum torque production.
• DFY5 high output units feature updated camshaft bearings that prevent hot oil pressure drop.
• High-volume oil pumps deliver sustained lubrication to cam phasers under severe towing conditions.
• Precision CNC-honed cylinder sleeves promote tight piston ring sealing and minimal oil migration.
• Multi-layer steel gaskets seal high combustion pressures against CNC-resurfaced deck planes.
• Reinforced timing chain guides eliminate chain slap during sudden throttle transitions.

Combustion Chamber Dyno Characteristics

This three-valve modular V8 provides relentless propulsion across 1,200 to 5,500 RPM, achieving 300 peak brake horsepower at 5,000 RPM and 365 lb-ft torque at 3,750 RPM. Camshaft duration measures 200 degrees intake at 0.050-inch lift, with 0.435-inch valve lift. Designed to operate on 87-octane pump gasoline. Idle vacuum reads 18 in-Hg at 600 RPM, backed by 45 to 75 PSI hot operating oil pressure.

Chassis Clearance Transaxle Integration

The rear block interface bolts straight to Ford 4R75E and 6R80 automatic transmissions without adapter hardware. Internal zero-balance design pairs with factory flexplates and dampers. The deep rear-sump oil pan clears four-wheel-drive front axle carriers, leaving wide clearance for long starter motors, steering intermediate shafts, and transmission cooler lines.

Maintenance Protocols Operating Boundaries

Pre-charge the engine oil passages with clean lubricant using an external pressure reservoir before startup. Fill the oil pan with 5W-20 fully synthetic motor oil and purge cooling air bubbles. This platinum long block is not engineered for aftermarket supercharger boost exceeding 7 PSI or continuous marine pulling duty.

• Discard break-in motor oil and install a replacement oil filter after the first 50 miles.
• Change engine oil and inspect variable timing solenoids every 3,000 miles of operation.
• Inspect cooling lines and coolant freeze protection every 12 months for thermal protection.

Factory Warranty Crate Contents

Protected by a 36-Month / 100,000-Mile nationwide limited warranty covering remanufactured components and machining. Crate packaging includes the remanufactured long block, complete oil pan, timing covers, cam phasers, dyno balance certificate, and an installation manual.
