I'm not sure how much research you've done on these cars...But you may want to stick with an 85-86 or 89-92...87-88 didnt have mass air and it will save you the time and money of putting one on cause for a nice running street car you will want it...and 93 mustangs they used hypertonetic <cant spell pistons which are weaker and actually the 93's produced less power...I've had a 90 mustang for about 9 years now and have not one complaint...I love it! Good luck with your search!
