I recently met someone who said he had a 96 gt with a built up 5.0 and c4. has anyone ever done this? im thinking compter, wiring harness, and motor mounts would need to be changed. my 5 spd should bolt up. any one have any suggestions? i have 130k miles on my engine, but the car is in beautiful shape. i was going to swap to 5.4 but i dont have the cash.

4.6L 
i wont have my 4V 4.6L S/C till middle of the year which will be a 03-04 kewbra
