340 Engine Mounts
Actually that is incorrect. You can shim the 318 B/E mount and make it work on a B/E 340 swap. As you said, it's just slightly wider. HOWEVER, the A body driver's side 318 mount is TOTALLY different from the 340 A body mount. It's actually missing the ear where it would bolt to the block.
Here's the B/E body 318 and 340 mount comparison.As you can see, a shim is a very simple fix on THIS mount!
The passenger side mount is the same on 318 and 340-360
