How long do you think it'll stay together? What do you think will go first, tranny or rear(s) (based on setup in Sig)? 700R4 rebuilt less than 10k ago (with a converter a bit higher rpm than stock), rears are stock 10 bolts, open carriers w/ 3.73's. 350 is rebuilt but fairly mild... not a ton more hp or torque than stock. Not too crazy off road duty... just light to medium stuff (i.e. I won't be beating on it). Thanks!
