I NEED some advice
 

Wats up all, my names Danny and i just got a hold of a 89 GT. i really luv the car but i know it has way more potential than wat ive done to it. #1, it has 148,000 easy miles on it. #2 i have added an off road H pipe and a underdrive pulley kit. I was wondering wat was my next couple of steps to increase my power. Maybe you could give me some advice on were i should start restoring since it has such high miles on it. Any thing would be greatly apreciated. Thank you very much

Well, kind of depends what your future plans for the car are...street racer, strong daily driver, drag car, strong cornering, etc.

But,first thing I would recommend for increase in acceleration is a new rear end gear. They don't give an increase in power, but you can really feel the difference when you get into it. I have a 3.73 in mine and love it!
