I have replaced everything and the slop is definitely in the box. I could just buy a rebuilt power unit, but I have thought about converting to manual. I have a 65 fstbk with a 289. Has anyone done this conversion? Do you get a more responsive feel? If you guys think I should do it, should I go with a rebuilt manual box or buy a new flaming river? Sorry this post is so long. Any suggestions would be appreciated.
