Considering a Fox Body. Which years are they best preferably a 87-93.
87/88's are speed density
87-92's are forged bottom eneds
so to me 89-92's are the ones to get.

What exactly is speed density?
Forged completely? Crank, Rods and Pistons?

Only the pistons were forged.
Get whatever you can get a good deal on. I am betting you are going to make a lot of changes any way. All of them need better brakes and a 5 lug conversion. They all need engine mods to compete with the newer V6 cars. And there is tons of good used parts for them.
