It takes 4 seconds to get an oil pressure reading after an engine has started running, so I don't think you are going to move the guage just by cranking.

My engine took quite a while to initially build pressure also.

FWIW, my 3800 engines used to have this issue, and I'd pack the oil pump with vaseline so that it didn't spin empty for so long, and that built pressure much more quickly.
