Tranny info and test?

[Ian1932]

Stopped at my dads on lunch break. Im trying to gather engine parts so everything is ready when im ready. There were several marked model B and some marked v-8. Some of the empty v-8 castings looked a little different than this one. A few had no guts. This was the easiest to get to so i grabbed it. It looks clean and complete as well. Can you guys help me with what i have here and if its what i should attach to a 34' flathead for a roadster?

Any simple tests i can do to see if its ok? It had a tag that said "good". That tag was probably of there for 50 + years...Would hate to use it without verifying its good. The engines and trannys are not my strong point...
