The special cam I measured assuming a flat face follower. It has 3 keyways and the one in the standard tdc position was used for the degree measurements. Before anyone asks, yes I double checked that I was rotating it in the correct direction. It runs in standard bushes and has no pressure oiling of the lobes Although the lift is the same as the 650ss cam it is not that. Does anyone have an idea of what it might have been used for? If I ever rebuild my 88 race engine I might use it but it would be nice to know if I should be advancing or retarding the cam somewhat.
The Extra special cam I know exactly what it is as I got the follower lift data directly from the creator. I just want to know if anyone can guess what it is.
I have another race cam that has the Dunstal type pressure oil feed to the lobes and runs in needle bearings and also has 3 keyways. I'll post details when I get around to measuring it.
Non of the cams have any identifying marks.
