I have a 91 gt aod with the following mods. 3.73 gears, mac shorty headers, mac off road h-pipe, mac cat back exhaust system, mac underdrive pulleys, mac cold air intake, 80mm maf, 70mm tb, trick flow track heat intake. should i get a 2400-2600 or a 2800-3100? i didnt know which would be the better size?

2500 it's not going to help a great deal til you have more in the engine..you need a transcooler to keep the heat down this is where bigger is better. with a 2500 advertised you be around 2200 for that stock engine

i running a holeshot 3000 stall. like the other guy said get the largest cooler avaible. i stall holding the brake to around 2400 and when i floor it it flashes to 3000 then launches. stalls are fun in stangs. traction will become an issue with the stall.<img border="0" src=smileys/smiley4.gif border="0">
