The 340 is out....again.....
So add an extra 1/2 pint or so of oil to make up for the pickup being off the floor. And you will be back up where you started with it on the floor. One reason I like to run big, remote mounted oil filters is a bit of extra capacity in the line and filter between the pump and engine in case the pickup burps; just that much more oil for the air to spread out in.... yeah, it's a theory LOL!
And like YR said: look at the pickup design. Most of the bottom is closed off by the way it is built. See here; having it touch the pan is not at all like the end of a straw against a flat surface.
