“Wiped Cam Reveal”

I wiped out a mini express purple shaft mushroom, but that was cause I didn't know what I was doing. Badly tuned crossram carbs, BIG vacuum leak. It didn't start right away, and I had WAY too much spring pressure for breakin.
Buh-by, now.
A friend lost a solid roller in a big block chevy. Valve springs went soft, put divots in the closing side of the lobes from the lifters bouncing.
