Well i got a v-6 mustang, Im researching about converting it to a v-8, probly a 5.0 motor. But was wandering what all im in for. I know i will have to change the gears in my tranny, and beef it up. BUT as far as the wiring harness go's. Is there an adapter i can buy?, I know i have to get a new chip burned. Im trying to keep from having to re wire the whole car. Anyone that has done this conversion or knows someone that did, could ya please fill me in?
