I just recently got my first mustang a 68 convertible with a six cylinder in it. I know it can't be orginal because it has an Egr valve on the intake. I was just wondering how to tell what size six it is and what year it came out of. I was wondering where the numbers are on the head and block. The numbers and letters I see on the block are EIBE and 6015-BB. Actully it is the first ford I have owned so any help would be greatly appericated. Thanks
