    Cant wait to see this conversion done. I was really thinking about doing this swap myself but that motor is just so heavy and really didn't want to do all the frame work.So i went with the 6.5 it's being built by a local diesel shop and we did a dyno a few weeks ago and it laid down 445hp so I'm pretty happy with those numbers so far. Got a built 4l80E trans and then after installed it's getting a straight axle and going on 37's
    By far a much better conversion and have a very good baseline and can do a lot more with power. And you'll have that amazing sound of that 12 valve. Awesome can't wait to see this done.

    Looks like an interesting project. Shame I don't have a car to put the old drivetrain into, otherwise I'd take that 6L and trans off your hands pretty quick.
