440 swap on slant six 73 duster

I used a motor plate from arengineering. And expensive tti headers. You may be able to use 62-65 b body log looking manifolds. They exit to the very back. I used them on my dakota and they should squeeze in. Dont take that as gospel. If you get some 73+ spool mounts and put them on the engine drop it close. Trans mount should keep you close. Try to keep the steering column in or nearby so you don’t have to run into that later. Have the bare kmember close. See what needs to be cut off. Whatever may interfere. Once you like where the motor lies. Tack the new mounts, box them in. Make it nice, get the right oil pan and steering linkages for bb. I had to do alot of pounding on new expensive parts for my first bb a body
