thoughts on the M11 Cummins?

[SFT21]

We have a M11 in an older IH truck that we use on our farm. Just had to do an in frame on it @775k but it is a good truck that’s had very few problems so we thought it was worth it.

OH here ran us right at 20k with a new head manifold and turbo.

Like others have said, as long as it is geared right they hold their own at 80k loads
