Default 3.8-4.6 4v swap

I have a 4.6 4v out of a mach 1 available to me. Im thinking of buying it and swapping out the 3.8. The transmission, rear end, motor mounts, wiring harness, computer, and hood are included in the deal. Anyone ever done the swap before or know how difficult it would be?

It wouldn't be too bad, especially since you have everything. You will need a fuel pump and possibly fuel lines.

Thanks. And im fairly convinced that 5k is a good price for all this as well. Right? Motor has around 40k.

Just ignore the Mark VIII specific stuff. Wiring will pose a different problem for you as you will need to replace the interior harness too. That guide will give you the basic idea.

You sure? I figured when hooking up the Mach stuff that it would be different, how the harness attaches to the interior harness. I may be wrong, but I thought the V6 was different.
