Iv just rebuilt the bottom end on the C16SE and have a new piper cam to fit but don’t want to sit at 2 grand for 20 mins running cam in with new rings/shells in bottom end. So I can’t see a problem with putting in an old 1.2 cam and followers while running in bottom end,it will be running twin 40s on the 1.2 dizzy.Any views on the would be appreciated
