I'm running 265/75's on the stock rally, measures a bit under 30". I'm happy with the 3.42, rear end is solid enough for my purpose. I just want to make sure I can leave black marks when I want, maybe a chirp every now and then if the mood strikes me.
I know I am not going to be patient enough to let my guys do this engine swap. Waiting to hear back from the guy who is going to rebuild my transmission, he said he would do a motor rebuild if I wanted, but also encouraged me to go with the crate motor. I'm gonna see what he might do the swap for instead. Give him my O'Reillys account and tell him to get it done!
