Modified Cam Followers

[Austin in the Shed]

For a road engine there isn’t a lot wrong with a standard cam and 3/4 radius tappets. People used to retard the cam slightly by using a stepped woodruff key but really there are easier ways of getting a bit more out of your engine.

I won class 1b in the vscc 4 years out of 6 and came 3rd the other two using a standard cam and 3/4” rad followers on a 11/8” SU on a ruby inlet.
