I stand corrected. I have limited experience with the 292, having only built one, over forty years ago. I have done a lot of 235/261's though.

I certainly plan on giving the 292 rod option another look when building a competition engine. I will have to see what the net weight savings between using a narrowed GMC rod and a 292 rod actually is. It may not be enough to justify the crank machining cost even though there would be a bearing speed advantage.

We are only talking about a 6,000+ rpm engine so the bearing speed is not really an advantage.
