I personally don't think that is going to be a problem, especially once you have 5 quarts of oil in there for it to swim in.

3/8"-1/2" is much better, 3/4" is too much.

i have a b&b oil pan that came with the screen but i cant seem to get it any closer than 3/4 inch from the bottom is there a screen that comes down closer or do the high volume pumps push the screen down any im stumped on this i was told any greater than 1/2 inch the oil swirls around to much

Are you using a high volume or standard volume oil pump? High volume pumps are physically about 1/2 taller. Most pickup/pan combo's spec out which pump to use. So this might be where the distance has gone.

Incidentally, how did you find that you had this problem? Kind of hard to see!

Sorry, misunderstood the question on my first reply- I have a high volume pump that came with my engine rebuild kit from Summit, and was lucky b/c it was virtually the same size as the original. Can you turn the crank by hand and make sure there's clearance between it and the pump?

My '52 hemi has a swing tube and floating pickup screen so the pick-up screen is always right at the surface of the oil. I think Chevys have a screw-in pick up tube that shoudl allow some adjustmeht to depth. Point is, can't you make some kind of adjument to the pickup tube? I would even go so far to weld in an extension of steel tubing B4 buying another pump.

All chevy pickup tubes are press fit, and can be moved, try to keep the pickup as level as poss.
When you have it where you want it ,spot weld the tube to the pump housing.
Iv`e seen more than one come out.

The tube/pickup screen is adjustable. I always turn the pickup tube way up (engine on stand upside down). Then I take and place the pan over it like I'm installing it without the gasket. Push down hard on the pan until it mates with the block. Remove the pan and push the tube down another 3/8". Then put the gaskets in place and install the pan. This has always worked for me.
