Description
Command 180 horsepower and 400 cubic inches of dyno-certified big block displacement while holding engine coolant temperatures below 200°F during grueling heavy commercial fleet transport operations inside this Ford 6.6L 400 Remanufactured Engine. Built for 1971 to 1982 commercial passenger haulers and utility platforms, this heavy 335-series engine incorporates a 10.297-inch deck height and hydraulic flat-tappet valvetrains.
Cast from high-density gray iron, this 335-series block features deep bulkheads and an Ra 30 micro-inch deck surface finish. Internals include an externally counterweighted nodular iron crankshaft supported by two-bolt main caps, heavy forged steel connecting rods, and flat-top aluminum alloy pistons. Bores receive diamond plateau honing with a 45-degree angle. Dry block weight equals 575 lbs with a six-quart oil sump capacity.
Key Features of Ford 6.6L
Commercial transport fleets buy Ford 6.6L remanufactured engine platforms to secure maximum operational uptime during demanding seasonal cycles. Machine tolerances follow strict AERA standards to provide uniform mechanical clearance throughout the entire rotating package.
- Large-displacement 400 cubic inch displacement delivers high torque for heavy commercial trailering.
- Two-bolt iron main caps hold line-honed tolerances within 0.0004 inches of factory specifications.
- Heavy forged steel connecting rods eliminate fatigue failures under heavy continuous cargo loads.
- Ford 6.6L high-volume gear oil pump maintains 50 PSI steady fluid volume to overhead valvetrain gear.
- Hydraulic flat-tappet camshaft profile optimizes low-speed pulling torque for vocational work.
- Moly-faced piston rings provide instant seal inside diamond plateau-honed cylinder wall bores.
- Multi-layer steel cylinder head gaskets withstand combustion seal stress under thermal load.
- Two-piece rear main seal matches commercial fleet manual and automatic transmission bellhousings.
Heavy Commercial 400 Combustion Metrics
Normal operating oil pressure maintains 20 PSI at hot idle and 45 to 55 PSI at 2,500 RPM cruise. Engine coolant temperature regulates between 180°F and 195°F through standard thermostatic flow. Power output measures 180 continuous horsepower at 3,800 RPM, providing 325 lb-ft torque at 2,000 RPM. An 8.2:1 compression ratio yields 140 to 150 PSI cranking compression. Heat rejection across radiator circuits reaches 4,450 BTU/min under Severe Commercial Fleet duty cycles across heavy regional freight corridors.
Heavy Duty 400 Driveline Alignment Specs
The traditional two-piece rear main seal crankshaft flange features a standard 6-bolt flywheel mounting pattern with external counterweighting. Crankshaft snout diameter is ground to 1.375 inches with precision keyways for damper installation. Dial indicators gauge crankshaft thrust endplay between 0.003 and 0.006 inches. Pilot bore fits Ford commercial transmission input shafts without modification.
Heavy Commercial 400 Break In
Use a mechanical oil pump priming tool to pressurize the main oil gallery until oil flows from every rocker arm before ignition. Fill the engine with SAE 30 high-zinc mineral oil for camshaft lobe burnishing. Not engineered for marine salt water use, supercharger boost pressures above 5 PSI, or vehicles exceeding 10,000 lbs gross vehicle weight.
- Inspect external oil pan seals and cooling fluid levels each shift.
- Check front accessory drive belt alignment every 50 operating hours.
- Change crankcase motor oil and spin-on lubricant filter every 3,000 miles.
Heavy Commercial 400 Warranty Details
Backed by our 3-Year / 100,000-Mile commercial fleet warranty against defects in material and remanufacturing craftsmanship. Shipped in a heavy-duty container containing the remanufactured long block engine, high-capacity oil pump, pickup tube, complete installation gasket set, pre-lube instructions, and dyno inspection sheets.
