Oil pump flaw is well known issue. Surprised you were running the car to 8000 rpm without a dry sump or upgraded pump? All early grand am motor failures were due to same issue. Classic failures from lack of oil. Grand am teams also measured drops in oil pressure around turns with stock pan. That's why they built deep pan with trap doors. But if I were to build an HR head motor I'd go for dry sump or not build higher reving motor. You really can't afford not to spend money on proper oiling if your building a track car motor.
It's why I'm went with forced induction until I can build motor with proper oiling system. What will you do on your rebuild to assure proper oiling?
