I6 crankshafts are longer, Of coarse it will need support. Your argument doesn't have much ground.....Example.....An I6 3406 Cat V.S. a V8 3408 Cat, Both will require an In-frame at the same Miles/Hours.

Put that Cat 4 cylinder in your truck & see what happens, Heavy machinery like Dozers don't idle very low either.

For the record I never put down The 6BT, I've owed 2 P-pump 6BT Dodges in the past, The stock LBZ Duramax I have now will walk any stock turbo 12 valve, Just a Smoke Show from the Cummins.
