My primary reason for asking are because of Dave’s comments about the measurements he’s taken not agreeing with the cam card. That, and the fact that the new cam “should” only have about .020” more tappet lift when the V/P clearance is closest. If he actually had .118” clearance before, the new cam should fit no problem.
So, either it didn’t have as much clearance as he thought it did with the old cam, or the new cam is somehow showing more lift in that part of the lift curve than it “should”.
The first thing I would have done when the new cam had “0” V/P clearance........would have been to slide the old cam back in and verify I had the clearance I thought I had.
Prior to even checking the clearance, I would have plotted the new cam out to verify it matched the card.
