If your asking us that you purchased a cam sprocket from Steve and If there is much differance? Yes there is. I have the one for torque. Smoother excelleration, smoother idle and it starts right up not even a full revolution on the motor. And I notice ther is no more low speed jerkeness.
While Steve does several different cam set-ups he only does one type of drilled cam sprocket which really does a great job of improving low/slow speed responce by improving torque by of of upping cylinder pressure.
