Got a low gear, why?

Ok, i finally finsih the auto to five speed swap. My stepdad has a 89' 5.0 and his gear is MUCH higher than mine.... why? I'm guessing maybe because the auto had a lower gear than the five-speeds? I put a stock T-5 in the car, not anything aftermarket. Anyway, anybody know what the stock gear is on a 90' automatic and a 89' five-speed? thanks.

rear end gear? final gear? which gear are you talking about.

AOD's, 2.73's or 3.27's
T5's, 2.73's, 3.08's or 3.27's

You will really have to look at the door tag on the drivers side door jam to find the AX code, then I can cross reference it for you.

almost all had 2.73's stock.
aftermarket gears are better for AOD, because AOD has more power loss than manual, so you feel it more.
