tried that , i get more valvetrain noise as it warms upand loses pressure . i was thinking mabe it needs a new pick up tube o ring or the mains being worn has and causing low oil pressure.
I wonder if it's overheating and not reporting it. Sounds like the oil is thinning out severely. Do you have access to a infrared heat gun so you can get some external measurements? What oil pressure reading are you getting at cold start versus when it warms up?

cold i get around 60 psi and goes down from there . it gets so low the warnig light comes on . the lifters will tick bad ,the i can cut it off and let it sit for a minute or two, then start it and the pressure will come up to 40psi and goes down to nothing . it takes about 5 mintues for the pressure to to be at 0.
Have you tried swapping to a new oil filter?

Yikes. Not good. The 6pointOh could be used for a 370 build.
The 4.8L will be a DOG below 4k RPMs or so with that cam and stock converter....
