Cylinder Head Volume

"It is also asking for cylinder head cc which I don't remember for the MEL."

You don't remember as there is no chamber in the MEL cylinder head except for the 462.

I am going to inquire tomorrow or MON at the dealer I used to work at and see if there is anyway I can get these engine values from the FORD rebuilder. I am going to ask for specs for a late fifties MERC engine and they are going to stare at me...watch.
