Go to fordcummins.com. I think people use the dodge motors because of some clearance problems with other engines. Also the 5.9 cummins is a beast of a motor. Also go to the second page and there is a thread called "diesel eng" Also the 3rd page of the engine swap forum "5.9L cummins in 78" You should also try a search, but the search feature is been kinda wierd lately.

i have a 99 7.3 powerstroke in my 76 crewcab 4x4 long bed. yes, i extended the frame in two places to get it all to fit(the long box 8ft). i ran the ford 5 speed from a the same two wheel drive truck i got the motor from. i kept the divorced np 205 and just had a new itermediate shaft made. i love it. its fast, get 18 mpg. and turns lots of heads. because we all know that old fords are even better with a little new technology. i ran a strait 5 inch exhaust, no muffler, no cat. took about about 5 seconds to get used too, it sounds bad A*$. i have had the truck on the road for a almost 2 years and 55,000 thousand miles with no problems. i used a hiboy frame and parts of the old two wheel drive crewcab frame to make it longer. i also had to lengthen the rear driveshaft. the cool thing is that it is longer than a 4 door longbox superduty by almost 6 inches. and impossible to park, and i wouldn't trade it for anything

Try to post links because the threads move around.
There are others here and in the swap forum that may have some good info in them even if it does not directly work with the 73-9's
