I'm thinking of getting a 5.9 cummins out of a 1993 Dodge for $700. It's of course the rotary pump, not the inline p-pump that the performance guys seem to like. I'm thinking it will still be ok for me though, as I'm not after a ton of horsepower, I am more looking for simplicity (ie. mechanical diesel) and reliability. Any thoughts on how these engines (with rotary pump) are for reliability ? Would love to put it in an old suburban, but so hard to find a pre-1988 3/4 ton suburban in decent shape around here.
