Can't say exactly, but I can remember getting my last set of Champion F14Y's in the late '70's. At that time, the F11YC's had already been sold out. However, the F14Y's may have long since been discontinued, but the auto parts store still had a lot in stock.
I can remember the auto parts store clerk mentioning that the lower number Champions were listed in his book for heavy duty trucks.
The last year Ford marketed the Y-block was in '64 and only for trucks. It's possible I was getting the last of a discontinued set of Champion F14Y plugs in '78. In '74, the last new Y-block (292 truck engines) were 10 years old. I still obtained F-11YC's back in '75, but that was the last time they were available here, then had to go with F14Y's and that was all that was available for the Y-block here.
