Welcome. Only you can decide what your goals/budget is, do you want a crazy build or just a cheap stocker? A KM132 is the go to tranny for a lot because it bolts right up and they are cheap and pretty easy to find. Don't think it will last for much power though. If I was building the engine I'd probably go with a Toyota W55/W58 or R154 at the least. Projectzerog.com( https://projectzerog.com/index.shtml) and their forum has pretty much all the info you'd need to do the swap, but I'm also more than willing to answer any questions if I can.
