I gotta say, Chevy engine have plenty of rod issues. When I used to drag race every weekend like a religion, it was a common thing to see BB Chevy engine chuck rods. It happened enough that it was sort of a truism people would toss around. Meanwhile, I ran for years on the same 6600RPM 440 that I never went into...in fact that engine is still in one piece. Stock rods, stock crank, Stock 5 quart oil pan. I changed oil every 2 weeks and drove the car properly. I have over 660 1/4 mile runs on it in addition to many street miles.

Personally...I think this thread borders on 'old-school fanaticism'. Use the biggest oil pump, the most pressure, etc. A lot of that thought is a Band-Aid approach to oiling. It might work, but it's not very hi-tech.

If you look at many modern design engines, they use 'oil management' as opposed to 'oil quantity'. We're kinda in that vein, too, but there's also a lot of 'throw as much oil at it as possible' going on.

I think a lot of 'oiling system' problems like bad rod bearings aren't oiling system problems at all. Rather, they are detonation problems, balance problems, material problems, missed shift problems, etc. that get blamed on the oiling system. Pushing the limits is a big part of going fast and racing...but exceeding the limits is a big part of failures.
