[QUOTE="timetraveller, post: 91091, member: 456"] You can't buy the cams or followers yet Vic. They are both my design and at the moment the cams, followers, ratioed rockers, modified valves with longer thick parts to the stems and beehive valve springs are with Mike Hawthorne to be built into his racing 500 engine and then to be tested on Ken Craven's brake. These cams were designed to replace Mk 1s. I have also lent Mike another cam, based upon the Picador cam, to give power at the 6,000+ rpm range and which will use the same follower as in the photograph. I don't want to claim anything for these cams yet until I have them tested in anger. Not knowing anything about cam design I designed them so that the acceleration while closing was the same as that while opening. Grey One has made me aware that this might be an error and that possibly the closing acceleration needs to be reduced in order to avoid valve bounce. We will see. [/QUOTE]
