Yeah but for the money you are going to spend on getting the 700r4 to work it would prolly be cheaper to just get the 60e with the LM7 they are pretty cheap and will make life a little more simple. Complete pull will also help your chances of getting a good harness/computer.
Also dirty dingo i wanna say makes some good motor mounts for your swap.
