No time to worry about Ford's garbage; I'm thinking about the wet-sleeve aluminum 225 in my '62 Lancer.

IIRC (waiting for Dutra's article to load) yep, I was right- the Al 225 isn't a "wet sleeve" design. Its got free-standing aluminum bores, an open deck head, and *dry* liners inside the freestanding bores, just like almost all modern aluminum engines do. Making it a "parent bore" engine.

Oh! Never heard the term. But I guess I get to go sit in the corner for having failed to memorise Dutra's article ;-)

True wet sleeve engines run the coolant directly on the back side of the replaceable liner. That requires some fancier sealing at the top and bottom of the liner, but allows for maximum heat transfer, which is why its usually only done on BFDiesels that run at max output most of their lives. 

Think the Viper V10 was one of these (maybe only the gen1 engine?).
