@Sacto Mitch: when adding the oil sump extension, whatever the brand, AND extending the pickup tube via a longer one piece tube or a slip-on extension, you can drop the oil level on the dipstick. But you'll still have MORE oil in the engine(1.5 quarts or more). I found that I lost the least due to slosh when I ran a 1/2 quart to a full quart lower on the dipstick, keeping the oil in the sump extension rather than the case.
When I had the CB thinline on there, I extended the tube with a kit from Dune Buggy warehouse. I cleaned everything well, then JB welded the extension to the tube(to prevent air leaks), and clamped the hose clamp on. Then I safety wired the clamp set-screw. Then I added a tubular spacer(with lots of holes!) and a big spring pushing the extension upwards. This is all to prevent ANY possibility of the extension coming off.
I removed all this when I went dry sump. The JB welded extension came right off and left no residue on the oil pickup. I never had any oil pressure variation with the extension. The dry sump system is an attempt to keep the oil IN the engine, as I was losing more to blow-by and breather than anything else. Hence new pistons and cylinders are going in to replace the 43K ovaled ones in there now.
