Experience classic supercharged acceleration by installing this Ford Thunderbird SC 3.8L Remanufactured Engine long block assembly. Built for factory supercharged performance coupes, this 6-Cylinder 12-Valve OHV engine solves notorious head gasket failure issues. A mandatory trade-off demands immediate cooling system vacuum filling and intercooler bleeding to prevent localized cylinder head hot spots during the initial supercharger boost pull.

Cast iron engine block carries casting numbers E9SE-FB or F1SE on the left side of the crankcase. Iron cylinder heads feature casting marks e9se-d78, f4e, or f3 with reinforced combustion decks. Crated envelope dimensions measure 36in length by 36in width by 36in height with an assembled weight of 267 lbs. Rotating components include crank casting E3 or F0, forged connecting rods, supercharged dished pistons, and a 5.0-quart oil pan.

Key Features of Ford SC 3.8L

Performance enthusiasts buy Ford SC 3.8L remanufactured engine assemblies to restore original Eaton supercharger boost response and eliminate combustion chamber leaks. This long block handles sustained boost loads while preserving original engine management sensor calibration.

- Heavy cast iron block decks are CNC-machined to Ra 25 smoothness to eliminate head gasket failure
- Diamond plateau cylinder honing creates deep oil retention grooves that seat heavy-duty piston rings
- Forged steel crankshaft casting E3 or F0 is micro-polished to hold 0.0003in TIR runout
- Align-honed main bearing saddles maintain 0.0013in clearance to protect bottom-end bearings under boost
- Multi-layer steel head gaskets clamped with high-strength bolts seal positive manifold pressures
- Supercharged camshaft profile is precision ground to original factory lift and duration specifications
- Rebuilt 12-Valve cylinder heads feature hardened valve seats cut to 0.001in concentricity for maximum seal

Dyno Load Precision Machining Tolerances

Dynamometer spin testing certifies 210 HP output at 4,000 RPM and 315 ft-lbs torque at 2,600 RPM under operational conditions. Machine shop tolerances enforce crankshaft journal runout below 0.0003in TIR and connecting rod bearing oil clearances at 0.0012in. Plateau-honed cylinder walls deliver uniform compression between 160 PSI and 165 PSI across all 6 combustion chambers. Hot engine oil pressure holds steady at 50 PSI at 2,500 RPM while regulated coolant operating temperatures stabilize at 195°F during full load machine heat cycles.

Vehicle Fitment Drivetrain Guide

This remanufactured long block fits 1989 to 1993 Ford Thunderbird Super Coupe and Mercury Cougar XR7 models equipped with the supercharged 3.8L 232 ci V6 engine and VIN code R. Matches rear-wheel drive systems backed by 5-Speed Manual or 4-Speed Automatic transmissions. Drivetrain note: this engine features block casting E9SE-FB or F1SE. It does not fit non-supercharged 3.8L Mustang models, front-wheel drive Taurus sedans, or 1994 newer Essex applications.

Installation Protocol Service Schedules

Prime the oil pump drive using an external hex tool before installing the distributor to saturate pushrods and rocker assemblies. Inspect supercharger bypass valve movement and bleed the intercooler circuit. Never run this supercharged long block with aggressive overdrive pulleys exceeding 12 PSI of boost without high-flow fuel injectors and an upgraded fuel pump.

- Fill crankcase with 5.0 quarts of high-zinc SAE 10W-30 break-in oil before initial crank
- Drain break-in motor oil and install a fresh oil filter after completing 500 miles
- Complete ongoing motor oil and filter changes every 3,000 miles to prevent bearing wear
