Dad and I put one together behind a JD engine about 6 years ago and remembering back I know Marathon makes some good generators and has/had pretty good reputation, so I"d give them a try. Going the new route that are also alot of others out there that are good also, you just have to take the time to seak them out.
Going the used route you could do some shopping at the military surplus sites and maybe come up with an old military unit since alot of them used Detroits, especially in marine applications. Too the RR"s used alot of Detroits so you might come up with something related to RR surplus if you looked around.
As far as the RPM you"ll need to be looking at the 1800 RPM units. One the Detroit isn"t going to like 3600 for an extended period. In fact I don"t think the 3-53 can turn that fast anyway, at least not under normal conditions but I"d have to check my book. Put it this way though I"ve never heard of a Detroit genset turning anything but 1200 or 1800 RPM. Too I"ve always been told that the lower speed units/generators tend to last longer than the higher speed ones do anyway.
As far as the governor you may need to change it depending on what the one you have is set up for. Detroit had variable speed as well as fixed speed models and you"d want the fixed speed one for a generator so it maintains the set speed of 1800 without varying too much. Too there are electronic governor controls available for many generator engines and the older Detroits may have something available for them.
As far as mounting if you know what flywheel and housingconfiguration you have you can often get the generator head set up for that engine. If not there are places that make adapters that can be purchased. I know there is a link on the Davidson Sales site in the tech talk section that shows drawings on how to tell what SAE pattern you have. Too, if I remember right, they have some good info too on sizing the generator to the engine, etc. As a company they also carry a pretty good line of generator controls, etc. All I"ve ever bought from them are alot of Nason switches and small stuff like that but they have always been really good people to deal with and always very helpful if called for tech help.
Below are a few links that might help you get started at least. There is another place that does the flywheel housing adapters and are more industrial related than the two i listed. I have done business with in the distant past but I don"t recall who they were and the link to their site was lost when my old computer crashed. In other words there are more than just these two so a little research should turn up some more if you need them.
Good luck.
