oil pan sludge removal

[JHFORD51]

I recently pulled the oil pan on my 39 Ford sedan with a stock 221 CID engine using Fordbarn advice and found the attached. About 1/2 inch of sludge in the bottom; I think the pickup screen was so clogged hardly any oil was being drawn into oil pump. Engine was otherwise clean--I guess all the ash and contaniments had settled to the sump over the years. Engine now has about 60 pounds at cold idle, 5 pounds at hot idle, and around 20 pounds at road speed. I think this is fair for an older engine with the original (pre 8BA style) oil pump.
