...Thanks Mike for the info

>would you imagine that there was a 'closed deck' M119 cast
and an 'open deck' M119 cast>>and there was not more work in casting between these blocks?

>or, would you imagine that the 'closed deck' M119 casting was the same for all M119's but the open deck was machined after the casting? If so, the open deck would appear to more labor intensive and costly vs. a simply cast M119 w/ no addl work ?

What would be the theoretical difficulty in consistently casting/cylinder lining a correct closed deck M119 that would yield a 90% production failure? how does the failure relate to the closed deck block production process?

Can you share where this information sourced from? Any details on this in the the Intro to Service manual?
