Early A Big Block And Motor Plate

stock B headers will hit early A idler arm if motor is placed in stock location. 67's and up seemed to move the suspension forward 2-3 inches as that is what it would have taken to get the Pro-parts passenger side to drop in unmolested. IF you could, see if moving motor forward 2-3 is an option for future header use if that is in your plans. You may want to build in a passenger side -1 bias off centerline for the obvious driver side steering shaft issues. Will have to move trans mount the same to keep parallelism. Or go with 3 U-joints and get steering shaft around the driver side manifold, probably easiest to engineer with least impact on everything else as those seem to fit well with that one steering shaft issue.

I'm not really looking at it from an exhaust perspective. I'm not sure I would gain an inch of room eliminating the stock mounts. It's more of a necessity thing. The 400 block I have has 2 mount lugs knocked off the driver's side. Not to mention the Schumacher mounts are expensive for one and unavailable for the foreseeable future for two, so I would kill two birds with one stone.

At some point, I wouldn't mind getting some measurements from you as to "where" the engine sits in the engine bay using the crank center line as a reference. That would help me locate the engine properly.
