Ok guys, Mike here.
We did get the info we were looking for on the journal bores.
Jack-Yes, you were correct with your last numbers.
Bill-I learned something I did not know either about the align boring.
Further FYI, apparently there is an organization called AERA. (American engine rebuilders association I think.) This is regarded by its members as the final authority when it comes to engines rebuilding specs. They have like 4 spiral bound catalogs showing different critical spec's. Each book cost like $100. Sure enough when the machine shop got their hands on these the 1955 and 1956 pontiac V8 engines were listed and their spec's. I did not want to push my luck with the rebuilder by taking pics with my phone.(Yet at least)
We are taking things one step at a time, and it feels like we are climbing the stairway to heaven! Thanks again to both of you for your help.
