Ford H/O 5.0L V8 Remanufactured Engine – 1985-1987 12742E

Description

A 50-ounce external balance factor combined with 45 PSI hot cruise oil pressure outputs 210 continuous horsepower to propel gross payload laden commercial fleet pursuit vehicles using this Ford 5.0L HO Remanufactured Engine. Tailored for 1985 to 1987 commercial patrol platforms, this inaugural hydraulic roller camshaft Windsor small block features forged aluminum pistons and high-nickel iron block construction.

Featuring seasoned high-nickel gray iron construction, this 90-degree V8 block features two-bolt main bearing bulkheads and an Ra 28 micro-inch deck finish. Internals include a precision-ground nodular iron crankshaft supported by two-bolt main caps, heavy forged steel connecting rods, and forged aluminum pistons. Bores receive diamond plateau honing with a 45-degree angle. Dry block weight equals 450 lbs with a five-quart oil sump capacity.

Key Features of Ford 5.0L

Municipal repair shops buy Ford 5.0L remanufactured engine platforms to keep high-speed patrol vehicles operating without mechanical downtime. Experienced engine machinists align-hone each bearing saddle to eliminate parasitic friction under grueling regional pursuit conditions.

• Factory hydraulic roller camshaft profile broadens usable horsepower throughout the 5,500 RPM band.
• Forged aluminum alloy pistons withstand extreme cylinder pressure spikes during high-speed transit.
• Two-bolt iron main caps hold line-honed tolerances within 0.0004 inches of factory specifications.
• Ford 5.0L high-volume gear oil pump maintains 50 PSI steady fluid volume to overhead valvetrain gear.
• Multi-layer steel cylinder head gaskets withstand 185 PSI dynamic combustion strokes without failure.
• Cast iron cylinder block casting absorbs continuous combustion thermal spikes during summer fleet runs.
• Diamond plateau cylinder honing provides rapid moly ring seat without cylinder bore burnishing.
• One-piece fluoroelastomer rear main seal locks motor oil inside the crankcase envelope.

High Output Roller Cam Ratings

Normal operating oil pressure maintains 20 PSI at hot idle and 45 to 60 PSI at 2,500 RPM cruise. Engine coolant temperature regulates between 185°F and 200°F through standard thermostatic flow. Power output measures 210 continuous horsepower at 4,400 RPM, providing 270 lb-ft torque at 3,200 RPM. A 9.0:1 compression ratio yields 160 to 170 PSI cranking compression. Heat rejection across radiator circuits reaches 4,100 BTU/min under Severe Commercial Fleet duty cycles across heavy regional freight corridors.

High Output Small Block Dimensions

The one-piece rear main crankshaft flange carries a 6-bolt flywheel bolt pattern with a 50-ounce external balance counterweight. Crankshaft snout measures 1.375 inches with standard keyways for dynamic balancer installation. Crankshaft endplay checks out between 0.003 and 0.006 inches using precision dial indicators. Torque converter pilot bore centers commercial AOD and manual transmission input shafts without friction.

Roller Cam Small Block Break In

Pre-lubricate oil galleries with an external pressure tank before initial ignition to coat all bearing surfaces and roller lifters. Fill crankcase with SAE 10W-30 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 7,000 lbs.

• Inspect external engine hardware and fluid levels with exact attention each shift.
• Check accessory drive belt alignment and tension every 50 operating hours.
• Perform oil changes with approved motor lubricant every 3,000 miles.

High Output Small Block Warranty

Protected by an elite 3-Year / 100,000-Mile commercial fleet warranty covering parts and block manufacturing integrity. The reinforced transport crate includes the remanufactured long block engine, high-output oil pump, oil pickup tube, complete engine gasket set, installation guidelines, and dynamometer balance test reports.
