I have a chance to pickup a Detroit series 40 engine with a p-pump. It is in an old Capacity Trailer Jockey. Is this the same as the DT 466? If so what kind of performance mods can be done to it? I am currently putting a 12 valve cummins in my 1982 Ford Bronco, and came across this and thought it would be a good score for a later project. Let me know what you'll think.
