Stock Forged Pistons in 5.0's

Hey guys, correct me if I am wrong (which could very well be the case :nice: ), but didn't almost all 5.0 mustangs up until midway through 1992 have forged pistons in them? I cannot recall where I read or heard that. If so, is there any way you can tell what you have without ripping the motor apart? I have a 1992 and I was just curious as to what pistons were in my car. Is there any kind of code in the VIN or anything? Just wondering. Thanks in advance.
 
It's said that up till about the last two months of the '92 model run, forged were what was in there.

A semi accurate way to tell is if the *factory* color of the oil pan is grey, it's forged. If black, they're hypereutectics.
