I have an America (790 cams) and have had a lot of discussions with Graeme from Thunderbike about his cams. The question I asked him was for cams for my big bore, that were an improvement over my 790 cams. The conclusion I came to was that he couldn't currently offer me anything to improve on what I already had. I thought maybe he has made some 790 cams and is selling them as an improvement over 865 cams(?).

He told me they were developing new cams with different duration and lift and that I would be the first to know when they were complete.......he never got back to me.
