Hey guys, question for anyone that can help. I'm putting a 302 in my 88 mustang. I found two 302's, one is a 90 302 out of a F150, the other is out of a 89 Crown Vic. Can anyone tell me what differences there are between these motors and a 302 from a mustang? ie,heads, pistons,I do know that the upper and lower intake off the mustang is different than the other two, but I still have the mustang one. Thanks very much, hopefully someone can help!
