741 Chunk

Hi all....I've never driven my 65 Dart with an 8 3/4 yet, but I do have a 741 chunk (non SG) Is it worth holding onto? From what I have seen over the years, it doesn't seem that they are that wanted. I'll be putting in a SB 408 with a 4 speed and going with a converted and narrowed truck D60 (overkill I know, but don't ever want to mess with it again) Should I put it out to pasture?
