Interesting, makes me wonder how it would do behind the P400 6.5s, unfortunately they're really rare, but I'm still a huge fan of the 6.5s because of how simple they are compared to the duramax and the size compared to the cummins.

With a whopping 250HP (with electronic control) I doubt it would be a game changer.

There is a guy who makes a ladder bar to reinforce the low end of the short block. That and P400 heads and a forged crank and you should be great.

Don't know, I can definitely see a difference in comparison with the 6.5 NA, that's an almost 100hp difference and probably has almost 2x more torque
