i have a fresh rebuild on my motor i have it running great timing is good vac is good just low oil pressure any ideas?

You verified oil pressure is low with a mechanical gauge?

How low is it and under what conditions?

Cold start the pressure should be 50+ psi.

Hot idle the pressure should be around 10 psi. Once hot, the pressure should increase about 10 PSI for every 1000 RPM your turning. So 20 psi at 2000, 30 at 3000, etc.
