Sorry Hank,
I don't have as much time as I would like to view all these posts.
We had Leo's motor tuned for around 600HP, and we didn't see any problems w/ bearings, and/or cap walk. The 292 has a pretty beefy bottom end, as I'm sure you already know.
We did this more as a security measure for when we start pumping up the boost. We were only able to muster about 12 lbs. of boost out of the turbo last year. But with the new turbos for this year, we will be pushing past 30 lbs., heading to over 1000HP. That's when I think it will really help us. Should eliminate any cap flex, and cap walk, which kills beaings.
This modification will help any race engine, or High RPM engine, but I don't think it is needed for most street applications.
What are you building?
