Chuck,
No BB engine built after the 1970 model year was designated as an L78 unless it was used as a replacement engine. CKO was not used in 1971. Never used in 1972 as well. Any engine used as a replacement was stamped CE. I would really question any 1972 replacement engine with a 1970 factory stamp. Please post pictures of the stamp and casting numbers. Rick H. |
