I have a 92 lx and i know that you guys have heard this post alot but i want to know all i need for changing my stang to a 5.0, and how much it might cost around.
You're better off asking this question in the 5.0 forum (because all of us in the 2.3 forum are obviously 2.3 guys). The price of swapping depends on a few things (mechanical ability, whether or not you've got a complete donor car, etc.).
To keep it short, search the swap topic in the 5.0 forum and you'll definitely find a multitude of information.
if you are doing a stock 5.0 swap, it will be far cheaper to sell the 4 cyl car and put the money towards a running 5.0. a decent vehicle will run around 2-3k. the avg cost of the swap it well over a grand for just the parts unless you can get them dirt cheap. figure in time/labor/ and you are easily in the range of buying a gt outright.
the parts you will ABSOLUTELY need
computer
harness
engine
gas lines
radiator

everything else should bolt up, but I highly suggest also swapping out the rear end, transmission, brakes, and suspension.
it's a huge job if you do it correctly.
