Joey50,
Absolutely. these mods should easily result in mid to low 14. I don't have any hands on experience with the aod but i believe if you shift it right 14's shouldn't be a problem.

You may also consider a shift light,it will help you make sure your getting to about five grand before you shift. many times I've seen slow et's as a resuly of short shifting.

Make sure you've done the usual; timing,silencer removed & so on.

Joey,
one more thing, make sure it doesn't shift into overdrive during the run.

It won't shift into OD because the AOD will not ever shift into OD at WOT when it is stock.
A 2400 converter will seem almost stock.
Either leave the stock one in or get a 3000.
I had an AOD '90 GT and 3.73's and a good tire was enough to run 14.60's-70's
Your AOD also will not hold out to 5 grand w/ out doing a 1-d-1 shift.
Hold 1st til you want it to shift...then go to "d"
Go back to 1 to hold second til you want to shift.
Then go back to "d" again and leave it there.
You should run about 14.30-14.50
Shifting like that w/ converter(3000)
shift kit, and 4.10's w/ tires.

I've got a 2400 stall and it is nothing like stock. 2400-2800 is perfect for a street car with no huge power mods. Mine prpbably needs to be re-stalled to 2800. Anyway, my combo works great. I can launch like mofo and can whomp most T5 out of the hole and it is over. 4.10, shift kit (Transgo or Baumann only), and a 2400-2800 converter = mid-low 14's.

Also, let it be known that the 1-d-1 shuffle that NOS_notch mentioned does work and will lower your ET, but it will kill your AOD eventually.

With a 2400 rpm stall speed you would be better suited with 3.73 gears. The 4.10's will work better with a 2800+ rpm stall speed.
