I agree, 80lbs cold idle pressure sounds pretty high to me.
That's what the car has though.
Here's the oil pressure rundown, when I had the car running at oil temps above 200.
Cold idle pressure 80lbs
Idle pressure 30lbs at 200 degrees
Pressure at 200-2500rpms 70-80lbs
Cold idle pressure 80lbs.
This why I thought maybe dropping a weight to 10-40 from 20-50 might be OK.
I've always gone by the 10 lbs per 1000 rpm rule, and my engine was definitely running higher than that.
