cast, forged, or hypereutectic pistons
Can anyone tell me what year ford switched from using cast pistons to forged pistons, and what year they changed from forged to hypereutectic pistons. I am looking to buy a low mileage engine, but I want to make sure that it has forged pistons. I am thinking that it was around 85' or 86' that they switched from cast to forged, and around 91' or 92' that they changed to the hypereutectic.
Thanks
