Made a long post about this already but it didn't seem to get through or was pulled for word choices. (I cleaned it up just in case.)
Here's a much shorter version.
Problem:sludge in water jacket prevented water from coming out.
After I removed the radiator hoses, I removed block drain petcock and threaded in a male air compressor quick connect into the block (same thread as it works out), and put the compressor's air hose to it and blew the clog free half way across the shop via the disconnected radiator hoses.
I removed the air hose from the connector and water drained freely and unobstructed out of the block like you know what.
