Doin a first project with a friend. 72 Dart. Going small block at first, but here is my question. I picked up a 999 trans from a co worker, and was wondering if a simple lock-up converter is all that is needed? I also have a 727 s.b. trans but was thinking the extra fwd clutch plates (in the 999) would be helpful. Not sure how Im gonna go, but any input would be helpful. thanx
