24v Questions

[notchbackgta]

I just got home from the junk yard. They had 3 24v Cummins in the engine area, already pulled out of trucks. I really wanted a 12v to put in a Suburban, but I think engines are only $140 each, so I am thinking I would take all three, even if to make only one good one in the end. They are just the engine for the most part, with accessories, I think one still had a transmission attached, manual, which is what I would want.
My question is, can I take the 24v pump off and any of the electronics and put on a VE or P pump and make it run that way? I am really new to the Cummins, I really only know what I have read here.
I have a search saved on craigslist and it emails me with all the Dodge trucks from 89 to 98 that get listed in my area, haven't thought much about the 24v as I wanted to keep electronics out of on old vehicle.

Any help is appreciated. Thanks
