Maybe the cam that I have (sifton 101) is not even intended for the latter model of shovelhead Maybe it's made for models up to 77 ?
harley made changes to the gearing in the 1977 on bikes - the only difference to the cams is the gear on it, the later gear had a machined groove in it so no mistake could be made in the install - the early gear is just flat on the face no groove
the dynamics of the cam it self is actually the same and you can switch the gears for your app - that cam you have is an old design is it junk NO is it less in performance that whats available today YES -
we have used the AB andrews cam you can feel it when it comes on in a 74 inch motor with an S&S and the 2 into 1 is an add to the mix - in an 80 inch motor the hit so to speak and its mild anyway is less because the motor is bigger - But it allows hydraulic lifters to be used -
if your build is on the cheap and that cam is not worn than use up, what you have in stock shovels, they are not big on being fast - LOUD sure - if its a just to be on and go for a ride, and your ok with adjusting valves once in a while leave it -- johnjzjz
