legally, no ...
Not without installing all of the emissions to go with the newer engine. otherwise it should be pointed out that it not be legal to drive, and therefore may be difficult to sell or may not pass an emissions requirement/inspection in the future. It would be just like a de-mandated truck would be if all the emissions systems were not installed to go with it. If done properly though, it could then be registered as a 'glider'.

As far as it being de-mandated, then technically it could be likely done.. but it would be a lot of work to the wiring to get it derivable again... likely leading to a whole lot of extra down-time while figuring it out.

Personally, unless you had a very significant reason to drive a flying brick, fuel pig of an out-dated truck (some type of special purpose vehicle that has unique or too expensive to duplicate in some significant way, like a boom truck, or some other specialty), then it would be far easier, cheaper, and quicker to sell it and go buy something newer and far more profitable in the end. Even if you have a unique situation, it still makes far more sense, if your really h$ell bent on keeping that particular truck, to put a CM870 back in into it, or to rebuild the one that is already there.
