Unless you have a lot of weight reduction... high 14s or worse... sorry...
Those gears are fuel economy gears... a freaking Town Car now comes with more gear than that!!!
I would get a 3.55L 8.8 rear from a junk yard donor ASAP... didn't 1985 GTs still have a 7.5 rear??? If I'm wrong and you do have an 8.8... get gears...
yeah but the thing is, is that i have to drive it back home to florida. I'm near dallas, texas woking with my dad i came out here because i didn' have a job back home and my car got stolen, so i bought an 86 mustang and had wells racing build me a daily driver motor so right now i can't put gears in it because i need to drive home and i don't wanna lose highway driveability. but i was thinking when i get home i went to put 3.55 no higher because it's my daily driver so what do u think that will put me at
