Mostly, the stuff that was already in production remained SAE, and the new stuff was metric. This started about the mid 1970s. Some of the old designs were used for several decades. You can still buy a new Chevy 350 engine (made in Mexico now) which looks and mostly interchanges with the 265 engine introduced in 1955.
