My 700 was going south so I pulled it and installed a TH 350. You give up a little in mileage but I don't drive fast enough for the OD to kick in very often anyway.

With that 4:11 your engine will be screaming at 60. I'd pull that and swap in a 3:73 and sell or trade that 4:11. With the TH 350 and the rear end you'll still need a drive shaft. I can't see punching a clutch in traffic where I live, so the automatic was the only answer for me.
YMMV
