Question stroked small blocks in the race cars?

It seems I have run across a reference that Ol' Shell had some strokers running at about 325ci displacement, for racing, but I did a search here and came up blank. Do any of you historians know of info on the FIA or USRRC cars that had bigger small blocks than 289ci in the early days? Perhaps it was later in the Mustangs?
