...the below 'narrow' wear pattern was from too tight a clearance!
.0023 to be exact, and that's a measurment from a used 'P' bearing...and I ran straight 50-wt! I'm guessing I originally only had .002 at the rods...how it didn't grab a bearing (especially with 50/wt) beats the heck outta me.
Just looking at it, everything suggested it was loose and only running on the top/bottom of the bearing.
Everything I've read told me P's had more room at the parting line, thus I thought that too was the reason for the narrow wear pattern. The shop that just line-honed my block(and miced the rods/crank) said the H bearing has more side clearance at the parting line...(my head hurts)...again.
Also, I was assured .027/.030 my side clearance at the rods is a non issue for oil control >I though for sure it was too much!.
