my son has a penchant for troublesome cars, at present a 93 Mit 3000 GT
[it will throw your @$$ back in the seat when running]
I followed it on the back of a tow truck to the [shared space] shop of the local expert.
wandering around while my son and the mechanic conferred I spot...
fresh from being ripped from somewhere...
a really big Onan where another fellow was charging the battery
one of those long thin [50s buick/clark fork lift] 12V batteries.
big push rod OHV V8 I did not recognize so likely a IH truck engine or???
Big 1Bl carb and a big gen end. too dark to read the gen end plate.
next time I will take a flash light and a camera
it looked relatively un-molested except some sort of aftermarket actuator near the carb.

If you get a look at model number, IH code is K, as in 85KR (an 85kW Onan with an IH 549 V-8 engine)

The thin 3E batteries were used to fit inside the skid base. Almost never used in new eqipment these days, but very common in the 60's and early 70's in machinery of all types including the JD 3010, 3020, 4010 and 4020 tractors.

There was also one with a Roi line engine on it. Don't remember the letter code. But it looked as big as a volkswagon.

Long thin 12volt batteries are still popular in the ag industry. They don't fit the kids cars so they seem to evaporate at a slower rate than normat car or truck configurations.

I wonder if it could be an old ford super duty v8? Back in the late 50's until the 70's at least, ford had a completely separate line of v8 engines for heavy duty use. They were called super duty back before every ford truck bigger than a half ton was called that. The biggest one was 534 cubic inches, and it made a little over 250 hp. These engines were designed for high torque at low rpm with durability. We know onan used ford engines, so maybe they used the super duty engines too?

The largest Ford engine I have seen on an Onan is a 460. The older big V-8's were commonly the IH and much larger Roline/Waukesha.

Sounds like a KR to me. Found one behind an old hospital that was being demolished; had a propane tank to run it. Had "boxes" in the side panels to accommodate the V8 heads, since the engine wouldn't fit inside the frame rails. Asked the general contractor what was going to happen to it; he didn't know. Gave him my card and told him I'd haul it off for him. I checked back later, and he said that some "doctor" wanted it - VERY large for any residential application. Would have been perfect for our office, though. Another Onan lost to - - where-ever.
