So I'm helping a local guy sell his 1977 Bluebird conversion. Nice bus and cool story (bought it new and drove it out of the BB factory!) Anyway, he special ordered (or specified the build on the bus) and got a V8 Cummins as opposed to the 3208 Cat. He said it is a wet sleeve engine and thereby better, probably an issue of debate for another thread. At any rate, he called it a "508", but from my research, it sounds more like a V903. Anybody out there care to chime in on this one. BTW, it is a nice rig, runs great and he is asking 10K if anyone has room for another rig. Hope everyone is doing well, Doug at 8000'
