you should seriously consider swapping in 3:73's or 4:10's...and do a rebuild if necessary...8.8 should bolt right in

I am going to try to find one with 3.73. Will there be some kind of tag that will tell me what kind of gears the pumpkin has, I know there is the door tag, is there a tag on the pumpkin itself, and do I have to change the speedo gear.

Get a pumpkin out of an automatic, it'll have 3.27 gears. Look on the tag & it should have 3 L 27 on the bottom row of characters.

If you want a steeper gear, you can get a 3.55 out of a 87/88 5spd Turbo Coupe or a 3.73 from the auto version. You can then install the ring/pinion/carrier in your IRS housing.
