110 Six oil pickup

This weekend I had a new diventure (that's actually a dilemma disguised as an adventure). I have a newly rebuilt 245 six that I have started 4 times...sounds wonderful. I shut it off, made some adjustments, started it back up and heard a knocking sound in the engine. I crawl under the engine while it is running and feel something hitting the inside of the oil pan. I thought maybe the oil pickup was banging the bottom of the pan. Cut the engine off, and each time I tap the bottom of the oil pan, another metallic sound echoes this on the inside. Surely, something is loose in the pan...baffle or oil pickup. I pulled the pan last night and see that the baffles are tight and oil pickup is still attached, but loosy-goosy on its pivot mount, and a gash on the top side of the pickup like the crankshaft hit it. I cannot visualize dimensionally the amount of clearance needed for crankshaft/oil pickup/oil pan, but certainly there is something not right here. Bent oil pickup? I have another old six that I could pull the pan and oil pickup from and investigate that. To deepen the curiosity, I noticed the dipstick from my 40 six had the oil level lines etched at the different point on the dipstick than my 41 six. Why would the oil level be different on these sixes, unless the oil pans are different, or perhaps one has the wrong dipstick.
Anyway, I wonder if anyone else has had an oil pickup banging problem, and what they did to correct it.
