does my 90 SC 5SPD have an 8.8" rear end? If so id like to get some better gears for acceleration. Am i looking to get 3.73's ? i dont want to get super crappy gas mileage , id just like to get her moving a bit quicker.

thanks lot
walter

p.s- just basically asking if 3.73's are most 5spd owners choice?

Yes, you have an 8.8" rear end. 3.73's in a 5-speed is a bit extreme. Most guys are very happy with 3.27's.

Yep the auto versions have the 3.27's already--alot easier and cheaper to just replace the pumpkin.

I had 3.27's in my 5 spd and changed to 3.08's a little less aggressive and very highway friendly! I think Lincoln mark Viii's have this same rear end with 3.08's in them.
