The HSC is an automobile
engine from Ford Motor Company
sold from 1984 until 1994. It was produced in Lima, Ohio, largely using tooling and designs adapted from the predecessor 200 CID straight 6

. Bore is 3.68 in (93.5 mm) and stroke is 3.3 in (83.8 mm). This engine produced 90 hp and 125 ft.lbf of torque. The HSC was Ford's first production "fast burn" engine.
1985 brought two significant changes. American-market engines received Central Fuel Injection (CFI), which reduced power to 86 hp. Ford remedied the power decrease with a High Specific Output "HSO" model, introduced for the high-performance variants of the Tempo (GLS) and Topaz (LTS/XR-5). Output was 100 hp and 125 ft.lbf of torque. This engine is denoted by an "S" in the VIN.
The early HSC engines were carbureted, with a 1-barrel Holley 6149 carburetor. Two-barrel Central Fuel Injection (CFI) was added in 1985. It was switched over to multi-port fuel injection in 1988 which raised horsepower to 95. Sequential fuel injection
was added for 1992 increasing horsepower to 98, but the HSO variant was dropped (as the sportier versions of the Tempo/Topaz received the 3.0 L Vulcan as standard equipment for 1992).
Applications:
. The extra displacement was needed to provide a four-cylinder engine option for fleet customers of the new Ford Taurus
. This engine used the head and cam from the HSO engine and produced 90 hp and 130 ft.lbf of torque. It sold in low volume (less than 15% of the HSC engines built) and was costly due to the tooling changeover required for the taller engine block deck height. It received sequential fuel injection in 1991, raising output to 105 hp and 140 ft.lbf of torque.
