Did see a four cylinder 1932 PB series Plymouth block running a Ford Y-Block head complete with an early aluminum ..Thunderbird Valve cover running at Bonnieville few years back. Think there was an article in an early Inliners Bulletin about it. Builder said he had to fill two bolt holes in the PB block and redrill them and the head bolted right on then. I have laid the two head gaskets on each other and it is right on the money. Thimking about doing one on my 1930 Plymouth four cylinder.
