Ford 5.4L V8 2002-2004 Lightning Supercharged SOHC 2 Valve Vin 3 Remanufactured Engine

Description

Command 380 horsepower and 5.4 liters of dyno-certified supercharged modular displacement while holding engine coolant temperatures below 200°F during aggressive commercial route and high-speed fleet transit inside this Ford 5.4L Supercharged Remanufactured Engine. Built for 2002 to 2004 VIN code 3 performance trucks, this Eaton supercharged platform features forged crankshaft components, lower-compression dish pistons, and deep-skirt iron block rigidity.

Constructed with a heavy-wall cast iron 90-degree block, the unit sports an Ra 25 micro-inch deck surface. A micro-polished forged 4340 steel crankshaft rotates within cross-bolted main caps, connected to drop-forged steel rods and dished forged aluminum pistons. Bores receive diamond plateau honing with a 45-degree angle. Dry block weight equals 540 lbs with six-quart crankcase capacity.

Key Features of Ford 5.4L

Specialized transport fleets buy Ford 5.4L remanufactured engine platforms to obtain maximum supercharged towing endurance without mechanical failure points. Machine tolerances follow strict AERA standards to provide uniform mechanical clearance throughout the entire rotating package.

• Forged 4340 steel crankshaft withstands continuous high-boost supercharger torque spikes without journal deflection.
• Lowered 8.4:1 static compression ratio prevents destructive detonation under continuous 8 PSI manifold boost.
• Cross-bolted four-bolt main bearing caps anchor the bottom end under severe payload acceleration stress.
• Steel spark plug thread inserts prevent spark plug thread ejection under severe commercial hauling.
• Ford 5.4L high-volume gear oil pump maintains 55 PSI cruising lubrication inside critical galleries.
• Multi-layer steel cylinder head gaskets withstand 210 PSI dynamic combustion strokes without failure.
• Diamond plateau cylinder honing provides rapid moly ring seat without cylinder bore burnishing.
• Fluoroelastomer rear main seal locks motor oil inside the crankcase envelope.

Supercharged SVT Dynamic Output Limits

Operating parameters require 22 PSI hot idle pressure and 50 to 65 PSI hot cruise pressure under load. Operating thermostat regulation maintains coolant heat between 185°F and 200°F during vocational service cycles. Dyno-verified output reaches 380 continuous horsepower at 4,750 RPM and 450 lb-ft torque at 3,250 RPM. An 8.4:1 compression ratio operates within 165 to 175 PSI cylinder pressure thresholds. Radiator circuits reject 4,800 BTU/min heat during severe commercial fleet operations across regional freight corridors.

Supercharged SVT Driveline Alignment Specs

The rear crankshaft hub incorporates an 8-bolt flexplate bolt pattern engineered for commercial 4R100 heavy-duty automatic transmissions. Front crankshaft snout measures 1.259 inches with precision keyways for dynamic balancer installation. Crankshaft endplay checks out between 0.003 and 0.007 inches using precision dial indicators. Torque converter pilot bore centers commercial automatic transmission input shafts without friction.

Supercharged SVT Pre Start Priming

Pre-lubricate oil galleries with an external pressure tank before initial ignition to coat all bearing surfaces and supercharger drive gears. Fill crankcase with SAE 5W-50 synthetic lubricant and bleed cooling system air pockets under vacuum. Not engineered for marine salt water service, aftermarket dual-pulley boost exceeding 14 PSI, or nitrous oxide injection systems.

• Inspect external supercharger drive belt alignment and tension each shift.
• Check supercharger intercooler fluid level and pump operation every 50 operating hours.
• Perform oil changes with approved motor lubricant every 3,000 miles.

Supercharged SVT Commercial Warranty Manifest

Covered by a 3-Year / 100,000-Mile commercial fleet warranty covering structural block defects and internal parts. The reinforced shipping container contains the remanufactured long block engine, high-flow oil pump, oil pickup tube, complete installation gasket kit, spark plug seals, pre-lube instructions, and hot-test dyno reports.
