Thread: water pumps????

New 180 degree thermostats 6 lb. cap, distributor is Mallory #3727501. Engine was rebuilt by both of us and magnuflux with no cracks, head gasket is good, timing is 34 degrees, carbs as stated are 2 94's on an sharp intake, mechanical fan is stock along with the shroud. The engine is in a 34 ford truck.

I ran a lot of flatties dirt trackers back in the day.The problem you have is with 2 water pumps it moves the water too fast before it has a chance to cool, we used to grind off every other impeller on the pumps,(since yours are new don't) use 160 degree thermostats first,the other old trick was to use fender washers with a 5/8" hole in place of the thermostats to slow down the flow.Probably the best thing is go to an electric fan that worked wonders here in Phoenix when I would stop with the A/C on.Good Luck!
