I don't believe there is a commercially available mount bracket available, (unless Andy F lists one) it's not a particlarly common conversion. A friend of mine was talked in to it, a whole lot of expense for very little benefit really.
He had an ATI dampener with a BBC front pattern, could run an off the shelf drive kit, rather than me having to machine one. I had to make the block off/inlet plate to go to the block in place of the factory oil pump.
His engine is going on to a chassis car, so I can't comment on whether it will clear the K frame.
