Is it hard to swap a v8 into a v6 1979 mustang? ?
its possible, but in order to make it as easy as possible, you need a 5.0 donor car like one with a wrecked rear or side, You need a motor a transmission all the wiring the computer, a drive line anda rear end. also starting with an automatic car is easier than a stick unless you are sticking with a 5 speed. Its doable but like any swap, it is usually a lot cheaper in the long run, to buy the car with a v8 already in it, than to spend a lot of time trying to fit and get everything right, especially if you have never done one. keep doing your research type v6 to v8 mustang swap and starrt reading, some years are easier to do than oters.
