The torque difference between the 865 and 904 with stock 865 cams is negligible.
I have run stock 865 cams in my 904 for a short time and was very disappointed in the results. The British customs stage 1 street cams i had made a huge difference.




I would have to agree with this statement as I did pretty much the same thing, 904 with 865 cams with the same sort of results. Getting rid of the stock cams is well worth it.
