A few points - (jmho)


The '94-'95 computers suck.
'94+ are pigs so put that thing on a diet.
Get some 4.10s and a sticky tire

Get a baseline of how the car runs now so you don't feel so bad when you sink some money into it and expect an impressive ET but dont get it. You'll have the baseline, so you can see the difference.

With the cons aside, if you really like the body style, you won't mind doing what it takes to get the number you want. If you want easy, these years aren't the best choice.
