Really? Because I’ve built my share of 8000 RPM plus small and big block chevy’s and the biggest issue is getting a decent pan on them.
I worked on the one time record holding BB/A Comp Eliminator small block chevy which is blown gas. He had to run a set sump by rule and it went through the lights at 10,500 plus depending on how the run went. He ran a stock pump. He had a nice pan and that was it.
When he was killing parts, knocking the rods out and fighting it in general it was 100% self inflicted. He had the 2 step set wrong, and it hurt parts in the first .5 of the run, but it didn’t knock the rod off until 600-700 feet out.
Once he corrected that it was flawless.
If a chevy isn’t oiling the rods, it’s because the nut behind the wheel changed something.
