Can you identify my engine?

Any one know how to identify what engine is in my 53 Studebaker Truck? The # off of the block is 527644. Thanks!

Thanks Denny. I have been to this site, but I don't feel like paying to be a member of thier club when I am a member here. I think when it comes to these clubs we should not have to pay just for info. Its nice to have a club where we just pick each others brains and help each other out for the fun of it.

Thanks, that did give me a place to start. I will post pics soon of my ride. I also have a 51 Desoto Firedome that I will post pics of.
