Kevin: We were just lately discussing this over at the Jockey Journal. At the same time, one of the respected posters there had put a Y engine on eBay, identifying it as a 67. Anyway, another respected member posted a scan of a BSA document I'd never seen before. You likely have seen the document, but I thought I'd try to point it out anyway:http://www.jockeyjournal.com/forum/showthread.php?t=91975
