427 engine suffix code, please help

[nobile motorsports]

Does anyone here know what this 427 is out of?
it is a 1969 date code 512 block. The suffix code is T08203CA.
I am new here and having problems posting so if multiples pop up I am sorry.
Thanks, John

By the way I heard this is the forum for answers.

No CA engine suffix's in 67, 68 or 69 cars. Could it be a truck or marine block?

Well, a truck block 427? I thought those were later used and were tall decks. Also the 512 casting wouldn't make sense. The only thing I can think of is a marine application. Hmmm...

This is a marine or industrial application.
