Anyone develop a radiator flow test without removing it?

It is not a trivial job to pull the radiator on a '37 Super Eight (or other similar late '30s Packard.

The 1937 shop manual specifies a 30 gallon per minute gravity flow and the 1937-38 Manual changes the flow to 36 to 41 gallons per minute.

I am curious to know if any reader has devised a creative way to run the test without pulling the radiator.
