guy ,you dont want a car that already has a lot of mods done to it,first of all if somebody is putting a lot of money in a 5.0 it usually means they are beating the shit out of it.im not saying its like that everyware but around here if someone has a nice 5.0 its pounded.try and find an old grocery getter 5.0 with nothing done to it.itll last longer and you can do what you want to do with it, not what someone else wants to do with it.take this advice from a former 5.slow owner and start with a virgin if you can.dont rush into anything!!!
