I have a 1950 Chevy 3100 Thriftmaster 1/2 ton, which is supposed to have a 216. I looked at the Old Car Manual Project web site - http://chevy.oldcarmanualproject.com/models/engine.htm

but couldn't identify the engine serial number. The engine I have says "DR140622CAL", which is different from the serial number layout on the above site site. Is there any other sources engine serial number searches?

The other interesting fact, is that everyone, including the old timers, has told me that the 1950 216 has babbitt bearings, which I understand to mean that the bearings are integrated into the piston rods and crankshaft main bearings. When I pulled one of the rod bearing caps off it had a bearing insert. I also under stand that the 1950 216 engine was a light blue color like the engine compartment, but the engine is orange. I'm wondering if the engine is a different year? Like I said above, I'd like to track down this engine serial number
