Awesome car, I'm excited to see where you go with it. If you want to do an overdrive transmission, the 727 Torqueflite 3-speed automatic was eventually developed into versions with overdrive and lockup torque converters. I always wanted to get a C-body Mopar, and swap out the 3-speed for something like a 46RH (later version of the Torqueflite) out of a rwd Ram pickup. The 46RH has hydraulic control of the overdrive engagement and torque converter lockup, and you can get kits to swap a newer transmission into an older vehicle and retain the overdrive and lockup functions (for example, https://transmissioncenter.net/shop/patc-727-to-518-46rh-conversion-kit-click-here-for-727-to-46rh-swap-wiring-diagram/) I don't know much about early Hemi's, though, so I don't know how hard it'd be to get a later Torqueflite to bolt up.

I had about the same opinion, mid 50's to early 70's, not really a fan of anything later. A few years ago I went to go look at a okay 1970 300 coupe, it had a little rust but looked decent and had a lot of options. Thought hard about it but didn't bite, still kicking myself a little for that. My current obsession is a 1965 300, that's the first year of the "standardized" C-body and you can get suspension and steering parts from them from Firmfeel, which is fairly local to me. (Fun fact: in the music video for "Love Shack" by the B-52's, the Chrysler convertible they're driving is a 1965 300) Like you said, any swap you do is going to involve some surgery. Even what I mentioned with a newer-model Torqueflite, if I put one of those into a car with a 440 (which is what I'd want in a car that size), I'd need to cut off the bellhousing and install a bolt-on one for the B/RB bellhousing pattern, the newer Torqueflite only had the small block pattern. If you're not afraid of the electronics, yeah that opens up many more late-model options. If you figure it out, it will be interesting to read about. I know some of the newer fuel injection retrofit kits (maybe Megasquirt stuff too) can control some elements of the electronic transmissions, but I don't know how much. Edit: Also, you might be aware already but there are addon-on overdrives for a variety of transmissions from companies like Gearvendors. Supposedly a reasonably simple install, although you need to shorten the driveshaft.
