Me and my friend need to replace the motor in his 1999 V6 Mustang. Can we just drop another v6 in it and it fire right up or do we need any other items?
4.0? 99 has the 3.8I just did a swap and as long as you are putting in a 4.0 and he year is the same it should just be a swap. If I were you I would replace the front and rear main seal, check the oil pump, oil pan, and any clutch components while you are doing the pull.
