Not a Ford guy, but can't you see the spot-facing and bolt heads on the outside skirt of the block?

Yup, and I sure do wish I had one of those crossbolted blocks in MY garage to get you a picture of!!!!!!! I've heard that a lot of blocks can be converted to the crossbolts, even found a place selling the main caps to do it.... Just not on my priority list right now, I guess...
But someday...........
