So Im finally at the gear stage and just installed 3.73's today and I am very veryimpressed in the difference there is in the car. My question is what is the spedo reading difference with my 3.73's vs. my stock?

I hope mine are going in this they have been in the garage for a month sitting in the box. are you going to do any suspension work

My suspension is done, its Napa and Ive got the adjustable rate springs, and they work awesome. The rear sags good on the launch.

check your door tag, "ax" m=2.73 z=3.08 e=3.27 for original

you'll be about 15-20% off right now

check http://www.ddperformance.com for a speedo calc or guide

Haha ya i know its a aod, but my fist stang, so im loven it. How much more do you like a 5 spd or an oad?

bro......it's night and day

here ya go....best times from all my cars w/mods

1990 gt aod ** 3.73, dynomax catback 2.5", gt40 intake, sprotsman pros, 1 5/8" shorties, ud pullies ------- 14.10
1989 notch 5-speed ** 4.10 , mac long tubes, flows catback, o/r h-pipe cai, et streets , 75 shot NOS dry --- 13.28 NA / 12.50 juiced
1988 notch 5-speed ** 2.73 gears 100% bone stock on street tires (120k on motor) -------------- 14.20's
1990 lx'vert aod ** 3.73, summit catback, 100 shot zex dry kit street tires--------------------------15.10 NA / 13.60 juiced
1993 notch 5-speed ** 4.10 , mac lt's, mac catback, mac prochamber, et street radials (w/ fuel issue)-14.00 NA/ 13.00 juiced

now the current car is times b4 dumping about 75 lbs, and fixing some vac leaks. i expect it to run just like the '89, it 60's better than the '89, but doesn't ET like it

we'll see

aod has a 1st gear of 2.40....t5 is 3.35 and it only begins there...i'm not ******* the aod, i tried to make it work, i went through 3 on my '90 GT and finally gave up, even got another aod car after that so wtf

but when it boils down to it.....it's a 5.0 and it's fun as he!! so be happy w/ it

nothing catches an eye much more than a red GT

** EDIT**

'90 gt best time was 14.40

and i forgot , even w/ 2200 stall, and motorsport lowgear set which bumps 1st from 2.40-2.84 and 2nd from 1.47 -1.55 + better od band it still ran 14.40's

that kit is basically the upgraded parts from an aod-e from a lincoln mark 8
