No oil pressure in the 1st 8 seconds, How to get turn of the key oil pressure Options

[Vietnam6871]

Engine is brand new 2.3 liter stroker that runs great except no oil pressure in the first 8 seconds then it runs fine with 30 lbs at idle and 60 lbs at highway speeds. Temp runs at 180 degrees normally with 210 being the hottest on very hot days. Any ideas on why it takes 8 seconds? Validated on dashboard guages and a mechanical guage. I can't drive this until I get pressure with the turn of the key.

If you route the oil lines with a high point near the engine you won’t get the drain back, but you will need to open the lines to do oil changes. Or you could add a drain valve at the low point.
