Re: 98 gt seeking more power
I've always heard, 3.73's for manuals, 4.10's for autos for most applications. I got 3.73's still in the box, just looking for a reputable shop for the install. Every bolt-on i've ever done has been a noticeable increase except the aluminum ds...couldn't really tell diff. good luck man
