The 6J27 is . . .
By Orin - 06/02/2005 4:21:55 PM; IP 198.107.179.90
. . . the casting date of the block. The date is 1966 (6) September (J), 27the day (27), September 27, 1966.
The C8ME-A is the engineering number used to ID the application. In this case it would translate to 1968 (C8) , Mercury (M), Engine (E). I don't know what type of block that would be. Try to measure the bore and post that number for addtional help from the gurus here.
But you still have to figure out how a 1968 engine ended up with at 1966 casting date . . . which would be a nice trick if you can pull it off. :-)
I suspect one of the 6s or 8s is being mis-read. Scrub it with some carb cleaner and take another look.
