Do you have a stock oil pump? HV pumps will bypass a lot of oil and the cooler may not help much. I have -10AN on my LT1-383 and a huge EARLS cooler. Oil still hits 285-300 after twenty minutes of open track running. Good synth oil
helps. German Castrol 0W-30 has stood up well confirmed by Blackstone labs. Mobile has a new track use oil with twice the zinc of regular oil supposed to be good up to 400 degrees but its about $ 15.00 a qt. Somebody try it and let me know how it works.
