I have a SOHC 4.6 and I really don't know that much about the 90's DOHC's. Do you know if they are aluminum blocks? Do they have steel cranks and forged pistons?
they are the Teksid aluminum block. forged steel cranks, cast cracked rods and hyper pistons. the only mod motor to get forged pistons from the factory that i know of is the 03/04 cobra.
