Shes got a Late replacement engine serial sequence number.
Sometimes they reused the CE engine block numbers a second time around and noted it by using the letter "A" in the Tonawanda pad number..Example:CEA60896.
Those are Pre 1970 production heads & intake too,they are wrong for the 1970 L-78 engines.
Looks like a Nice L-78 Manual.
Where are all the L-78 Autos!
