Jimi, did your marine blocks come with the Hemi caps and machined for the side bolts? I have a marine block and it has the bosses cast into the insides of the pan rail, but it is not machined for side bolts and has regular caps on it. Mine doesn't have a casting number on it anywhere.

Did you run those blocks in SS with a MW? I was wondering if the side bolts would be legal in SS on a MW engine?
