A 364.5 and batmowheel 480 tows well and has plenty of power to spare. Just ask JoshH, it's on his shop truck. That thing spools insanely fast!
I ran a 369/488 setup for a bit on my LBZ. It's definitely not something I would tow with often but it would get the job done if you have a built motor. Way overkill for a stock bottom end. A 366/480 or similar is not bad. Russ ran that for years towing and running 11's in his ccsb with a stock bottom end and 40% injectors. It's flat out hard to beat a stock/475 or 480 setup for towing and daily driving though. Hands down my favorite for street manners and all around functionality for a stock bottom end. A very close second would be Josh's 364.5/480 setup.
