Wiped Cam Lobe Theory - Imput Wanted:

Wiped a lobe once putting a new hydraulic lifter on an old cam. Totally stock 383 4bbl.
Put lots of STP in the 20w50 oil, but didn't matter.
Lifter wouldn't stop ticking even after removal and solvent flushing as recommended, so I chanced it.
Took about a week before I could tell one cylinder was off power.
