The owner's manual, workshop manual, and spare parts catalogue all mention the 83mm (1991cc) option for TR4.  I assume that was only
to homologate them for strict under 2 liter racing classes, but surely they had to deliver at least a few of them.  There are even
"83mm" cylinder heads listed, which I'm guessing had the smaller combustion chamber (to maintain a 9:1 C/R).
