Hey guys, I have a 1977 Monte Carlo that I built a 383 stroker motor for and the 350TH that I have in it has a 10" 2800rpm stall converter in it. My problem is that it never seems like it locks up, constantly slipping. It goes through the gears a little faster than I would like and when it goes into third gear, I have to let off the throttle a little bit to get it to slip into third.  I am thinking about installing a 700R4 transmission, Would a 400TH work as well? I haven't taken it to the tranny shop since they rebuilt it, back in 2010.  I have a 10-bolt posi rearend with 3.42 gears.  If I choose the 700R4, does anyone know of what mods I will have to do to install it.  Any help would be greatly appreciated. Billy
