For the 398 CID build I'm into, I'm consider using piston rings I haven't used before and am hoping someone has used them and will give me some feed-back on them.

They're: Speed-Pro R-19100s and Perfect Circle 315-0036

I'm going to write this last part, even though I know up-front that it won't be heeded, but I'm only looking for feed-back on those two rings. Not alternate/substitute recommendations like "You should use blah, blah, blah". PLEASE!

Thanks,

Jake
