not that i know of, i called a ih dealer here in missouri and they said the 361 is the factory replacment for an 806 even tho you cant get that engine anymore. there has got to be some kind of replacment engine for it tho i just dont know what it is as im sure you already know 361 and 407 parts are getting extreamly hard to find and i am buying anything i can find for them, we are running a 806 with the 361 in it and we are running pretty good.
If you go according to CaseIH's parts system, no, a DT466 is not a factory replacement engine for an 806. IH did not offer a "kit" that could be ordered to install a 400 series into a 806. Along those same lines, a 407 is also not a factory replacement for an 806 or 1206, just as a 466 is not a factory replacement for a 1066.
