On the 03 4.10s is a good all around gear but 4:30s are more fun. On the 93 3.55s are the way to go. Some may argue 3.73s but they really kill your first gear. On my 92gt I walked and a lot of cars with equal mods exept for gears.

sounds good. the old man and me decided to step it up some so were both getting some new stuff. he decided to go 4.30 on his mach 1 thats just a bit to much for me lol

On a Mach 1 4.30s is the perfect gear. There was a member here about 2 years ago (pete) who had a Mach 1 with 4.30s and cams and ran hi 11s at the track but unfortunitley they broke into his shop and stole the car.

for your 03 i had 410's and they were a lot of fun (in my 04). but i did at times wish i had 430's. but i now have 430's in my 08 gt and i wouldnt go ANY LOWER or ANY HIGHER for that matter. for your 93 i isay 373's

03 - 4.10's if you're trapping below 110mph or don't plan on trapping more than 110mph. 4.30's if you're below 108mph or don't plan on being over 108mph.
93 - 3.73's i believe will allow you to trap around 125mph on 26" tire. If you're not skeered, then 4.10's. :burnout:

i have the 4.10s in my fox now but it revs way to fast through the power band. the 3.73 seem to be the way to go. Watching how trevor04 launches and runs im liking that set up a lot
