Before you spend any money on that block, you may want to first secure a way to mount it into the chassis. The 2 bolt bosses were probably deleted from the mold that block came from. The now defunct Indian Adventures use to sell conversion motor mounts, I don't know where you can get them now, I made my own when I needed them.

Before buying the rod bolts, you may want to ask your machine shop if they will even install the bolts and recondition the rods, most shops do not want to mess with them considering the cost of an import H-beam rod these days.

Ring gaps are critical due to the way the piston expands, common to pop the tops off of them regardless of brand engine they are installed. Nothing wrong with the cast pistons, I shifted a couple motors with them at 5800 for years.
