The engines with the 4" Mercury cranks are worth more - if the blocks and cranks are good. The only way to know that is to do the complete disassembly, hot-tank, magnaflux, pressure test and mic everything. There is no such thing as a 'Mercury Block' from 1946 - 1953 - they're the same as Ford blocks. The Mercury cranks from 49-53 have a 4" stroke and if they're good cranks are usually worth a few hundred bucks each (depending on journal sizes).

In the end, it comes down to how much work do you want to put into them, do you have the necessary tools, skills and time to do the hard work . . . because it takes a lot of time even with the right tools.

In the end, it is really more of a labor of love, versus a highly profitable adventure . . . and there can be a lot of "boat anchors" found along the way! LOL
