I have a 6.5 i just rebuilt, and i plan on replacing my 6.2 with it.  It is in a 71 chevy half ton right now.  When i swap them out Im going to put all of the mechanical stuff of the 6.2 on the 6.5.  I also am going to put a mechanical 6.5 pump on it.  But the major thing im going to do is put 3 turbos on it.  Im going to twin it with little air research turbos, put both of them into two separate after coolers then dump it into a big cummins holset turbo and block off the wastegates for all of them.  Im guessing that it is going to produce about 800 ft lbs of torque or so.  and get about 30 miles per gallon. What do you think?

Sounds very ambitious and quite cool. ironically that is the concern i have. 6.5s have a nasty problem with cooling issues. having that much boost will be quite a handful for the internals. may wanna do some research into extra cooling capacity (water pump, rad etc) to make sure you dont cook this beast of an engine from the inside. Best of luck and keep us informed

Cheers

You're going to use head studs, yes?

800ft/lbs of torque should be easy to obtain, but that much boost is gonna lift one or both of the heads off that block.
