I needed better oiling to maintain oil pressure in long sweeping turns at 100+ MPH. I added a Milodon racing oil pan with trapdoors to keep the oil by the pickup plus a big block oil pump and this immediately worked better providing great oil pressure in high speed corners. I'm really pleased with the Milodon oil pan improvement.
The longer term solution, after my 1970 Z28 IROC street/race Camaro is built, is a complete rebuild including a dry sump.
