Russ, 
For what it's worth. I wouldn't worry about it. That's not atypical
for our Scout engines. If the lifters aren't complaining loudly,
you've got lubrication. I use 5-50 synthetic oil to try and help the
oil pressure, and it wouldn't hurt for you to use the 10-40 instead of
the 10-30. 
If your gauge is mechanical, it may be taking that long for the
pressure to get up the capillary tube.

< IH everyone, 
<  got in last night from a beautiful weekend in the
< Guadalupe mountains in west TX. Gorgeous scenery, and
< pretty high (for Tx, 3000 foot peak, great hike).
<  Question: I changed my oil before we left Friday
< night. It was the first time I cahnged the oil in my
< Scout (finally hit 2500 miles, figured I'd do it
< before the long trip). 
<   I put in 10W-30. My oil pressure is now doing funny
< things. When cold the pressure will take a while (10
< sec. or so) to come up to around 45 on the
< after-market mechanical gauge (dash one doesn't work).
< Once it's warm, at idle the pressure drops to <10, and
< at highway speeds (2600 rpm's) it will only reach
< 30-35.
<   I am thinking I should replace the 10-30 with 10-40,
< but I am also concerned with the length of time it
< takes to build pressure when cold. Should I
< rebuild/buy a new oil pump? Can this be done
< 'in-truck'? i.e. without pulling the motor?
<   Any help and advice welcome!!
< TIA,
