I have a 97 600 with 46,000 miles on it. I am thinking about putting a 99 750 in it with less miles. I know they are both SRADs and am pretty sure the swap would work. This engine comes with the computer, wireing harness, injectors, and all else except the guage pack. I can pick up one of those sometime though. Has anyone heard of this swap or know someone who has done this?
