How do I mount to engine stand?

Thanks, Sireland, I was gonna mention that. Got "downtown" and buy some threaded rod, grade 5 if you can get it, some nuts and a big pile of 3/8 USS washers. US "through bolts" as in the photo through the large unthreaded holes in the bottom of the block, then saw off some rod and screw into two of the upper threaded block holes. 3/8 US course thread.
