Define 'original'.
Tonawanda built 182 ZL-1 engines; 71 were used in production. There were just under 600 blocks cast; highest machining # I am aware of is 505 so scrap looks to be about 14%. The majority of machined block castings were sold to engine builders. If it is an 052 or 053 block cast [late] in 1968 or 1969, it was part of the program.
