914 Water pump, Yes a SBC Options

[drive-ability]

I'm replacing my Renegade/Chrysler BB pump, since it locked up last night. I didn't here any noise at all ? The engine does make a bit of noise but you would think there would be some warning. Nope ! Maybe something broke off and jammed up the impeller etc. The pump just locked up and melted the drive belt.
My question is I have been running a standard pump and decided to get a high volume unit. My assumption is the quality is better than my last one and with A/C it might perform better moving more water. I guess with more pressure comes it own set of issues. One thought is the belt was too tight, and that's a good bet.
I'm not running a Thermostat but am running a minor restriction in the thermostat housing, which I think I should remove.. ?

Any one have any input here. (IMG:style_emoticons/default/type.gif)

It's sorta like when you use a paint spray gun on a 50 ft air hose, you gotta crank the pressure up to about 80 psi to get the gun to atomize the paint like it would with a 20 ft hose. The other option is to use bigger water lines so the restriction is less and that would reduce the effort at the pump. try it without a thermostat and if the water is moving too fast start using a restrictor till it cools. Then you will know whether or not you can use a thermostat. If the thermostat was closed or had too much restriction a stamped impeller would probably bend at high rpm.

I have a 63 jeep j200 truck with a sbc. When I was trying to get it to run cooler I tried a flowcooler waterpump and eventually blew the tank off the radiator. The flowcooler waterpump basically has a plate on the back side of the impeller to move more water through the pump.
