    So I test fit my 440/a833 combo in my 72 dart today. I'm using the Schumacher sb to bb conversion mounts. The oil pump land right on the crossmember mount and keeps the rubber isolator just off the crossmember. I'm sure i'm not the first one to run into this. What have you guys done to remedy this issue? Thanks in advance.

      Has anyone built a solid mount that is a little bit taller than the factory biscuit so you dont have to clearance the crossmember? Mine is powder coated and honestly I'd really like to avoid cutting it up.

      I have a few pictures of the car we did it too but none of them get a close-up of the oil pump at that Tower but you literally just mark it as you can see and cut the whole front part of it off and then just stencil, cut, and weld a new plate in.
      Mock up is important for this reason.
      I bet a few dozen members here can help you with a pic.
      A couple ways, I chose the complete removal.

        Don't the instructions for that kit show how to modify that mount?

          Maybe. I bought this kit a few years ago and then the whole project sat idle for years. I just found on there website where it talks about it. That's my bad. I'll modify the crossmember like they recommend.

            That link that dart 360 sent is the exact one I used. The engine has to be out ( sorry) then drill the holes in the corners first, then I used a cutoff wheel and connect the holes you drilled. File and paint.

              Ah okay, that makes sense. If you leave a project sit for a few years then it is hard to remember all the little stuff like that. It is also easy to lose instructions and misc parts like nuts and bolts. My Duster sat in the shop for 7 years until I finally got around to working on it. I had to go thru each box of parts and lay everything out so I could remember what I had. Good luck with the project, good to see that you're making some progress on it now. Keep plugging away at it.

                How about a flat spacer between the biscuit and the k frame. 1/4” aluminum plate with a hole or slot in it. Put one on both sides. I’ve done this on small blocks for header clearance.

                  This is what I was first thinking but it would need to be quite a bit thicker. Probably 3/8" to 1/2" to account for the movement of the rubber mount. I going to end up trimming the crossmember like they recommend.

                  Check out the pictures in the 383 engine mount thread in this section.
