AOD advive!!!!

87mustanggt · 08-30-2001, 05:16 PM

i have a 87 mustang gt with the AOD and 2.73 gear. My best time so far is 15.34 at 92 mph, it was about 95 degrees out and i have a vacuum leak in my upper and lower plenum gaskets when i ran this time. Im planning on swapping my gears to a 3.73 or 4.10. I was wondering what time would i get with the new gears? Also, would 4.10 blow the Aod or the rearend. I hardly ever drive on the highway if that makes a difference.. Thanks

I bet everyone here will tell you to go with the 4.10's and rightly so. Mine used to be an aod and i had both gearsets. The difference is night and day. I loved it. But I loved it twice as much when i finally got rid of that oversized paperweight behind my engine and inserted a manual z-rated t5.

It depends on your future mods. Go with 4.10 for a N/A combo and 3.73 for S/C or NO2.

if you plan on staying n/a, then get 4.10s. that works out perfectly, as you say you don't drive on the highway much, so you shouldn't notice a drop in mileage, just more shifting.
