Then put a good oil pump in the engine with a 70 psi relief spring. I'd put a high volume pump in it with anti-cavitation slots, but that's just me. Then you could probably run a decent 10W30 racing oil and be just fine.
Why didn't you say the oil pump was intentionally modified in the first post? It would have saved a ton of time and effort.

Please read the first post again
Sorry, didnt mention that it was modified to have less oil pressure.
"The motor have a stock GM modified oil pump (anti-cavitation grooves)"
The rockers isnt blue, they looks just great
I have looked at this pump, what do you think about this pump?

Its a Anti-cavatation design pump, but it says "Using this oil pump will reduce pressure at idle"
Is it any problem to drive this pump on the street with the reduced idle oil pressure?
