I think that all that needs to be done is drill two holes in the bottom edge/lip of the plate on the front of the block (the plate behind the crank/cam gears). The 47-55 truck engine's front motor mount is attached through those two holes.

Maybe someone has a picture or a link to a tech tip?

use the plate on your 216 as a drilling template?
