5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
93+ had hypereutectic pistons. Not as strong as forged but they have less expansion which means they have less gap between the piston head and cylinder wall. The gap was required on forged pistons because on start up the piston head is smaller than at running temperature.
93 engines were still called H.O. if i remember correctly...
