Hey guys, my dad has a 92 suburban w/ 305, it has a bad bearing and the tranny is almost gone, if possible where are some local shops where he could take it to have both done, also if its possible he would rather convert to a 350 and th350/400, our family has been through 4 4l60s between our 3 trucks in the last few years and thought maybe the th350/400 might live a little longer. let me know what you guys think, thanks,

Bryan
