Torque Converter Color mean anything? And some other weird findings!!!

So, i pulled my engine and trans today, the transmission, a small block 727 was changed/repaired decades ago because the tail shaft and housing got eaten so i knew it was not the original, but i was wondering a few things.

First i decoded the numbers on the case, and it matches to a 69 or 70 dodge truck, not what should be in a 73 Roadrunner, does that really matter, gear ratios maybe different?

Second, it has a B&M sticker on it with some numbers, i am assuming this is for a shift kit that was added to it at one time, but who knows if its still in there.

Third, does the color of the torque converter mean anything, its turquoise and i dont see any numbers to identify the configuration for stall speed.

any feed back on any of these please let me know, the entire unit is going to be rebuilt, but i just wonder what the heck i have!

Thanks
