I'm not one to throw out recommends too often but my new mechanic has been very very good doing my 455 engine and TH400 tranny swap. He was pointed out to me by my brother who didn't have time to help and he's been very meticulous and really cares about getting things done right on these classic cars. If you're in the Newmarket Aurora Bradford Richmond hill area give him a look see. I'm not sure this is the right area to post but I figure if not someone will move it.
