Sbc very low oil pressure. Use thicker oil?

Hey guys the 350 in my car has very very low oil pressure at hot idle. Cold idle its very good. Hot idle in gear is literally sitting just over 0 on the gauge. In neutral it comes up to like 4 or 5psi, then when cruising it looks ok. Just slightly under 20psi. The annoying thing is that it doesn't have many miles since rebuilt. I was thinking maybe the filter is clogged, but I didn't think that it will affect oil pressure, at least not this much. I was thinking of getting a fresh filter and some thicker oil and seeing what that does for it. What would be a good oil to get? I would think 20w50 is too thick. It has 10w30 in it now. I don't know if 10w40 is a big enough jump to make any difference. Any help is awesome. Thanks
