The trials cam in my Ulster engine was done by Pigsty. It certainly does the business with masses of low down torque but it is as noisy as hell, even with standard followers as recommended. I am not an expert on cams but two pals who are looked at it and both said it was quite severe and had no quietening ramps. If I wanted another modified cam I would go to Paul Bonewell.
