I believe that 86-92 HO 5.0 engines in Mustangs had forged pistons, both models. I think in 93 they changed to the Hypereutectic cast pistons.


If you need further proof, you might check the 82-93 Mustang GT Registry

It was a 5.0 in the mustang Between 87-93 it was an H.O. All 5.0's in 87-92 had forged pistons. Trojan is correct as in 93 they changed to hyper. Pistons. The lx, the gt and the 93 cobra got those pistons. Those new pistons stayed in all 5.0 and 5.8 engines until production of those engines ceased.

So the 86 are or are not? I've heard that 86 has forged pistons but there flat top pistons.

Yes, the 86's are forged, flat tops. You can find the info on the website link to the Registry.
