Thanks fellows!
Some good information. I have found the serial number and it is T214SR-0129.

From the internet research that I have found, this id's this engine as a 1942-1945 military WC series engine.

I'm going to start a new thread to offer this engine for sale.

Thanks,
Dan S

Hello. This is my first post on the g741 site. I am a jeep guy who needs some power wagon help. I have an engine that I would like to offer for sale soon. I think it is an M37 or WC engine. Can you take a look see and tell me what you think a fair asking price would be. Here is a link to the images....
