Why do you want more flow? From what I've learned about cooling systems you want restriction in the flow.

of coolant in the system. The amount of coolant flowing through the system. And the amount of air flowing through the fins of the radiator. If any one of these is improved a little better cooling is noticed. If all all are improved then the engines will run cool. I have performed cooling tests on flatheads for many years in SW Florida in temperatures above 90 degrees. I have a 39 P/U that was run at a National Ford meet in Maryland in about 2004 for over 2 hours at a fast idle with the outside temperature over 100 degrees and never got over 180. When raced slightly the temperature dropped a few degrees. This truck was fitted with Skips pumps, 6 blade industrial fan, standard radiator, 4 lb pressure cap and a shroud. Temperatures were taken every 10 minutes on the water outlets of the heads and recorded. Don't believe water has to stay in the radiator to cool it, that will just make it hotter. G.M.
