Ford 5.4L V8 Truck F250,F350, Excursion SOHC 2 Valve Vin L Remanufactured Engine

Description

Exhaust manifold stud shearing and torque converter hub vibration under 350 lb-ft sustained cargo towing disrupt commercial freight deadlines until precision line-honed main saddles stabilize rotational geometry inside this Ford 5.4L Super Duty Remanufactured Engine. Built for heavy commercial fleet trucks and Excursion chassis, this Performance Improved 2-valve engine pairs cast iron block rigidity with 8-bolt crankshaft driveline integration.

Cast from high-nickel gray iron, this 90-degree V8 block features deep-skirt cross-bolted main bulkheads and an Ra 25 micro-inch deck surface finish. Internals include a forged steel crankshaft supported by cross-bolted caps, forged steel connecting rods, and flat-top hypereutectic aluminum alloy pistons. Bores receive diamond plateau honing with a 45-degree angle. Dry block weight equals 520 lbs with a six-quart oil sump capacity.

Key Features of Ford 5.4L

Fleet operators buy Ford 5.4L remanufactured engine packages to sustain demanding schedule routes without unpredicted mechanical downtime. Each production run adheres to strict AERA machining tolerances to maintain factory operational performance across regional routes.

• Heavy-duty 8-bolt crankshaft flange handles extreme vocational payload towing stress without flexing.
• Performance Improved cylinder heads optimize intake air velocity for enhanced commercial pulling torque.
• Steel spark plug thread inserts prevent spark plug thread ejection under severe commercial hauling.
• Ford 5.4L high-volume gear oil pump maintains 50 PSI steady fluid volume to overhead valvetrain gear.
• Single overhead camshafts actuate two valves per cylinder through hydraulic lash adjusters and roller followers.
• Multi-layer steel cylinder head gaskets withstand 190 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.

Super Duty Truck Combustion Ratings

Operating parameters require 20 PSI hot idle pressure and 45 to 60 PSI hot cruise pressure under load. Operating thermostat regulation maintains coolant heat between 190°F and 205°F during vocational service cycles. Dyno-verified output reaches 260 continuous horsepower at 4,500 RPM and 350 lb-ft torque at 2,500 RPM. A 9.0:1 compression ratio operates within 170 to 180 PSI cylinder pressure thresholds. Radiator circuits reject 4,350 BTU/min heat during severe commercial fleet operations across regional freight corridors.

Heavy Truck Transmission Interface Dimensions

The rear crankshaft hub incorporates an 8-bolt flexplate pattern engineered for commercial 4R100 and TorqShift 5R110W automatic transmissions. Crankshaft snout measures 1.259 inches with precision keyways for dynamic balancer installation. Radial dial indicators confirm crankshaft endplay between 0.003 and 0.007 inches across all thrust surfaces. Precision-ground pilot hub bores seat commercial torque converters without radial runout.

Super Duty Truck Pre Start Priming

Pre-lubricate oil galleries with an external pressure tank before initial ignition to coat all bearing surfaces and roller followers. Fill crankcase with SAE 5W-20 synthetic blend lubricant and bleed cooling system air pockets under vacuum. Not engineered for marine salt water service, forced induction turbocharger systems exceeding 6 PSI boost, or gross vehicle weights exceeding 14,000 lbs.

• Inspect external engine hardware and fluid levels with exact attention each shift.
• Check external oil cooler line fittings and hoses every 50 operating hours.
• Perform oil changes with approved motor lubricant every 4,000 miles.

Super Duty Truck Commercial Warranty Details

Supplied with an industry-grade 3-Year / 100,000-Mile commercial fleet warranty covering parts and block casting integrity. The heavy-duty shipping crate contains the remanufactured long block engine, high-volume oil pump, oil pump driveshaft, complete install gasket package, pre-lubrication instructions, and certified quality audit dyno sheets.
