Hey guys, it has been a while since I have been on here. My 4x4 background is mainly with Yotas, and haven't had one for a couple of years now. I decided to pick up an old 1962 International Scout 80 that's in pretty good shape. It has the original I4, I believe it is a 3 speed T13 trans, and a Dana 18 t-case in it still. Engine was rebuilt, re-installed and it has just been sitting since. I am trying to decide what I would like to put into it, and am leaning pretty hard towards a GM V6, maybe 3.4 or a 4.3 if I can find one cheap, and looking to stay carbureted. What I really need help with is what manual transmissions/t-cases, good for offroading of course, will bolt up to the engines without using any adapters. I haven't found a good website yet that shows multiple options. I have found lots of info on NP231, SM420, etc, but I want to know what you guys think. Thanks!
