From my information. . . the 7.3 PSD is not a variation of some gas motor. But even if it were. . . who cares? It must have been a damn good gasser!

So whats the big deal, the B series Cummins diesel is a variation of a gas engine.

Button pushed! Actually, the B series is not based on a gas engine design. But, there is a CNG/LNG version of the 12v. called the 5.9G. It was developed well after the 5.9 diesel came out.

ive seen old IH diesels in tractors that start using gas or kerosene, then once up and running switch over to diesle. this was before glowplugs were out, so they need the high octane to get the thing turning, then they went to diesel
Several John deere tractors used this system also. The engine was started on gas then, once warm you manually flip the tank switch and it runs off of kerosene. The larger deere tractors,like the 830 , Use a small gas engine(called a pony motor) to start the big diesel. These are very good tractors.
The 5.7 GM diesel was indeed a converted Olds 350. The diesel block is still sought after by racers. It's thicker castings make it ideal for spinning it too fast for it's own good. They tend to not break. I had a gas olds 350 in my '79 98 regency. You could shift from first to second at 65mph and not blow that motor up. Unfortunately the diesel version didn't do well in the cities where it was supposed to get better mileage. It would overheat, blow a head gasket and then it was junk. A lot of people used 427 or 307 olds motors in place of them.

In diesel form that's about right. You have to remember that when they came out there really weren't any turbos on diesels yet in cars, and the VW 4cyl made a whopping 45hp, the Nissan 6cyl made around 60ish hp, and the MB 4 or 5 cyl made somewhere between 50 and 70hp (don't remember off the top of my head). They were all DOGS but they got 40 to 50 mpg. The Olds 5.7 in gas form was a pretty good engine, they'd run almost forever (I know mine had 180k on it and still carried 40psi of oil pressure at idle, and 60 or so cruising). It wasn't the best off the line, but it had decent hp coming in around 160 or so.
This is an assumtion on my part as I don't have facts in front of me. Ford may have saved redesinging the hood, engine compartment by using the shorter V8
engine. I would venture to guess the inline 6 cyl Cummins must be about 8" longer.
Also the MRS tractors used by the Army Corp of Enginners was driven by a IHC
semi- diesel started on gas and turned over to diesel when warmed up. MRS by the way stood for Mississippi Road Service Tractor .
