The 7.3 IDI is a much heavier built engine then any GM made 6.5. The newest 6.5s made for the military have been beefed up quite a bit but that doesn't count.
7.3 has a forged-steel crank, all gear-drive in front, heavy cylinder heads with hardened valve- seat inserts, heavy block, etc.
6.5 has a cast-iron crank, chain drive in front, light cylinder heads that WILL crack when the ports get hot, a light block that will crack at the main-bearing webs after X amount of miles, etc. There is no way to fix the main-web cracking problem. GM tried with later 6.5s by making the outside main-cap-bolts smaller thus leaving more block metal. It helped but did not fix the problem. I would not trust any 6.2 or 6.5 for long-distance travel unless the oil-pan got pulled and the main webs got checked for cracks. Once they show - it's ticking time-bomb. Often around the 200K mile mark.
I still have my 1994 IDI turbo 7.3. 350,000 miles on it and the engine has never been apart. 4WD, extended cab, long-bed, 4.10 axles, E40D trans. Gets 17-18 MPG empty on highway in the flatlands of Michigan. Gets 16 MPG in hilly New York.
I've also got many 6.2s and 6.5s. Running and blown-up with broken cranks and blocks. I like them because they've always been easy to buy cheap.

Today's Featured Article - Women and Tractors - Tractor Engine Repair - by Teri Burkholder. One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I’m handing him tools and he says, "give me that..." and I’ve already got it in his hand or "hand me that....."and I’ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th
