Hi there. just found this 318 block , supposedly a 67.Casting nr same as race block but is not . but the casting at the main caps are usually machined and this looks different ,also 5;th cap has a larger oil hole than usually .someone got an idea?

If that is a truck block with 4 hole motor mounting on each side....it will likely bore 4.04 Casting number to look for is in the bottom pic, that's the ticket....
