How quickly should oil pressure come up?

Cranking the motor does not spin the oil pump fast enough to build pressure. It’s not a good practice on a stock motor. If it was dry sump and had an external oil pump that’s one thing…..

I'll think about that next time I spin mine over to fill the carb after all the gas has evaporated out from setting for a few weeks. In a perfect world we would all have fuel injection or at least a priming pump to help the engine start faster. I can't help but think that 300 or 400 cranking rpm wouldn't pick some oil up and send it through the crank.
