My buddy has a 94 mustang with a 3.8 and it blew a headgasket, he has found a low mileage 3.8 out of a 2000 model will it fit. I know the intake must be changed but is the shortblock the same. I don't know much about the v6 mustang and neede all the help I can get on this subject so he doesn't waste his money.Thanks
