Thanks for the response. The 235 currently in the dump truck leaks oil faster than I can put it in. Although the truck is used very little on my farm property, I would like to also have a more dependable engine. The reason I am investigating the Jeep engine is that it can be had for very little. What it will cost to fit it in the dump truck is unknown. A straight swap would be nice. I will consider Chevy 261.
