Big Block Motor Plate - Bolt to ideas?

My motor plate on a big block 500 CI stroker motor just bolts into the block by the water pump and bolts.

Does someone make one that bolts all the way down further on the block or a couple bolts further down? Anyone tackled this idea?

I had one that also used some timing cover bolts.

I made mine to bolt just to the water pump housing bolt holes. However, I also have a miplate as well. It also mounts to my snout bars and ties to the frame rails as well.
