You guys have been great helping with my new '37 Chevy 1-1/2 ton stake bed. I am still having trouble tracking down what engine it has in it, though. The number is really funky, and I can't seem to locate the same prefix, or similar numbers in any of the engine lists.

The number is:
ECM207722

Has anybody seen anything like that before? Are there different engine lists for the heavy-duty trucks?
