According to my research and with Baltimore build sheets the changeover started mid December 1969 and was mostly completed by early February. I have a December 12, 1969 LS6 with a 768 pump and have a February 4, 1970 with a 727 so for unknown reasons both pumps were installed in that time period. I have had March Baltimore Chevelles in the shop with 768 pumps.
