I've done it in my '87 GT. I'm using a '95 300 HP engine with Getrag transmission. I'm running it with 275 HP chip (only one at the time that could work with a manual) and 2" dual exhaust, so it's a little down on power.
I don't know my 0-60, and my top speed doesn't concern me (It'll go to 120 easily, and that's not even topping out 4th gear). My best 1/4 mile is 13.3@103 or so. With the 300 HP chip, larger exhaust, and better tires, it should be able to crack 12's.
An automatic car, even with the electronics working correctly will be somewhat slower as it will be 200 lbs heavier.
Lots more out there. Use the search function. I've documented a lot of my swap here on the forum.
