Oil pressure issue

I have a 4.3 liter that I am having issues with. I have changed the oil to mobile one 10 w30 synthetic oil and running a k&n oil filter the same one for a 350. My issue us when it's cold I have oil pressure about 30 to 35 lbs and when it warms up it is about 20 to 25 pounds. Any ideas what could be wrong and how can I fix this? My other Chevys run between 60 and 80 psi
