cummins in 71' chev longhorn

I have a 71 chev longhorn 3/4 ton. Has a 402 big block with a beefed up 700r4 automatic and 3:54 rear end LS. I love this old truck- it has every factory option, but is very thirsty-especially when pulling my fifth wheel. I now use my 91 E350 dually CTD.I would love to put a 6 cyl cummins into it. Has anyone ever heard of anyone doing this or has any info about it? The tranny cost me big bucks to have built -extreme duty clutch packs,torque conv,shift kit and a few other mods. The mechanic told me it would take alot of torque, even if the 402 was opened up from its stock 400 ft ponds of torqe. I don't know if the tranny would be applicable for this application or not. Any advice appreciated. Thanks in advance. Dean- whitecourt, alberta, canada
