Ugh! Think I screwed up my rings
Asleep at the wheel. I was knocking down the corners of my rings and ran a small bevel on the outside edge, not just the corners. Afraid I’ll get too much blow by now.
What do you say, yea or nay? I’ll gladly invest in another set if needed.

That’s ok.
The thing to not do when rounding over sharp edges with a moly face ring is to run whatever your abrasive tool is back & forth, as that done on the face of the ring can flake off the moly. You want to only make you passes by pushing in to do the rounding off.

Yeah, the top ring is moly, so made sure not to run the file out while filing, just in.
Won’t I lose compression by that bevel, or just not enough to matter?

How’s the top and second ring to piston back clearance?
They should not duck into the groove by more then .005”

I figured only a few thousands was going to be exposed between the piston and cylinder wall, and that’s exactly where the bevel will be of course. Still OK?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
