It's a 4wd 80 from another truck I have... The 205 is in the Burban behind a TH400, and I think it should work if I can run the tranny... Maybe standalone or a full manual valve body setup? I was just going to use the speedo cable that is there in the T case. The only reason I'm debating this is to run the BBC with the 4.10's. It's getting 35x14.50 boggers and the poor lil 350 has lived a good life but must retire. I might try out a carbed LS in front of the TH400 as I would like to keep the BBC and straight axle the other truck... Best advice I ever heard was "One project at a time" wish I would've listened, lol... Thanks for the reply your truck is a bit of inspiration for me to tell you the truth, You are on FSC too if I remember right?
