How many people have wiped out hyd or solid cams and the damage sustained. I have read more about people wiping hyd cams on the PY forums in the last 2 years then I have seen in 35 years dealing with Chevy and Fords.
Most solid roller lifter deals with wiped rollers is due to the excessive pressures needed for high rpm and making hp. Or people not keeping a check on the increased lifter adjustemnt needed and then realizing that something must be happening.
This isn't the issue with a hyd roller to which this topic is about.
No high rpm break-in required.
I can change cams and use the <span class="ev_code_RED">Same</span> lifters over and over.
