there is absolutely nothing wrong with the a-0 models. I own one I have worked on a few and the warrant officer I worked with on deployment said the a-0 was the better truck for reliability. The problem with the non electronic motor is finding some one old enough to know how to diagnose and repair it with out a computer, some times the nerds still cant fix them just replace sensors thinking the problem is electronic not a mechanical problem causing the sensor error. Schematic wise the fmtv is frightening compared to a duce or m151 but the a-0 is still much simpler than the a-1 with the 3126 0r c-7 engines same with the first gen Allison transmissions the 4 and 5 th gen transmissions can feed you a lot more information for diagnostics and even run prognostics to tell you when to change your fluid. that however comes with a price more wire and more complex tcm. I was happy to get what I wanted an a-0 mechanical engine, but I own my own cat software and wouldn't be afraid of a 3126 or c-7 all the early problems wit the a-0 models like drivelines and bell housing bolts should have been fixed while in service. If you are looking for being able to ramp up horse power the processs is a little more simple with the electronic engine as long as you can get some one with cat e-t and access to factory passwords to do it, it takes a little more work on the mechanical engines for real hp numbers above 275, but up to 275 all you have to do is remove the valve cover and adjust rack travel after that one must start thinking about injectors and induction mode or melting a pistion becomes a real possibility.
