Billet Tappet Cuff Kit M8

[Ohio HD]

Just rotate the cam till each lobe is at full lifter under the lifter. Set the cuff on. If you can move the lifter upwards before it hits the cuff, all good. Check each lobe. But I doubt that you'll have issues.

I assume the .600 and .610 numbers are valve lift and not cam lift.  Valve lift is cam lift plus rocker ratio.

These numbers really don't tell us much.  Too many variables that are unknown.  A cam with a 1.5 base circle and a valve lift of .610 will move the tappet to a height in the bore that is the same as a 1.45 base circle with a valve lift of .615.  The difference being how for down in the bore the lifter is allowed to travel.

I agree Jason. The valve lift is a number that most can understand, but really isn't the number that's important. I assume all S&S cams will fit under the cuff, no matter who's cuff. But that's just my assumption as they don't list any cams not to use in the instructions. They just say to check for clearance.

I'm going to guess these also require proprietary pushrod cover tubes?
