The third-generation Mustang was produced from 1979 to 1993. Built on Ford’s ubiquitous Fox platform, it evolved through a number of sub-models, trim levels, and drivetrain combinations during its production life.
For 1987, the Mustang received E7TE heads and valve-clearanced pistons. The E7 cylinder heads were sourced from the truck line after the 1986 swirl-port design demonstrated performance problems. Power ratings jumped to 225 hp and 300 ft·lbf (410 N·m) of torque. No major changes were seen in 1988, although the T-roof option for hatchbacks was discontinued midyear.
