I am going to be looking at a car that supposedly has a Ford Racing crate engine built with the Boss block. How can I verify that it is actually a Boss block from the outside? I know to look for screw in freeze plugs but is there anything else I can look for?
Its a little hard to see, but this will be enscribed on the bottom near oil pan. I believe there may also be something enscribed on the front of the block as well.
