Help with Flathead ID? year?

I recently acquired a fairly complete engine.
Serial numbers are C1BA on the bell housing flange. E1879 stamped into the top of the block. EAB and Made in Canada cast into the heads.

researching on the 'net I come up with either a 49 or a 51... not sure which and no idea what vehicle it came out of.

any ideas? thanks in advance

 

yeah 49-51 canadian ford..... its an 8BA style.

 

Heads are from '52-'53.
