This topic is never going to be laid-to-rest ..... 
Bearing and rod-side clearances ? .... ALL of this is a "leak" in the chain. For someone to say that there is no diff in this RSC "leak" between 10 and 60 ....... is uNsane ! 
WHO was talking about 007 ? .... WJ. And IIRC ...from that article ... he ran a steel rod motor at 11 all the time.
I am 100% in agreement with this. It may get THROWN easier out of a larger clearance, but NO MORE OIL than the vertical bearing clearance allows will come out if you have .030 or 3/4 of a mile of RSC. The contol of oil flow at the rod IS the vertical bearing clearance. If we have a leak that is .035 GPM, and we are running it into a bucket with a 1/2" pipe, THEN take thew SAME .035 GPM " leak", and rdrain it in a 3/4" pipe, are we leaking MORE oil? No. Its still .035 GPM. Its just running thru a bigger pipe,that will not matter UNLESS we have blockage in the pipe and so forth. If you have a vertical bearing clearance of .0032, then THATS what you will get for oil. Will it fly OUT of the offending .060 side clearance faster than the .030 side clearance? Maybe, but its STILL whatever oil is passing thru the .0035 vertical clearance.
Rod vertical bearing clearance is what meters oil flow, not the side clearance... not today, not tomorrow, not ever.
Don't believe everything you read, WJ does not have any steel rod motors.

I wish that someone like Barton, Hughes or Koffel would come-on this topic and put this to REST.
But to say that RSC has NOTHING to do with oil-flow is just flat-out wrong. Again ...it is just another "leak" in the oil-supply chain.
No disrepect intended to any of your heros, but we did some experimentation in regards to bottom end clearances at a place I used to work at, and didn't see anything like you are claiming. Share your testing results, and I'll share mine.

Large rod side clearance is not gonna hurt anything other than as pointed out windage and oil that ends up in suspension.
Well Big Al ... that Xtra windage and oil-in-suspension costs power.

I have no testing results ...so does that mean that you will not "share" yours ?
But if RSC is of no importance ....WHY does any Mopar service manual OR any type of HP build magazine/book I have ever seen calls for a max of 19 or so ?
DOES anyone have a AndyF Mopar book ? ... what does HE SAY about this ?

358 endurance race motor, switched from .012" to over .100" rod side clearance. Same block, same crank, same pistons, same bearings, same oil system, same oil pump, same oil, same oil temp = same oil flow & same oil pressure.
Your manuals and magazines say more oil is coming from between the rods with over .100" rod side clearance, why didn't oil gpm go up and pressure go down when these rods were put in after the .012" side clearance rods?

The only way rod side clearance is going to effect your oil pressure or volume is if it is less than your bearing clearance.
Getting old just means you were smarter than some and luckier than others.
