340 Water Pump questions, anyone using Flow Kooler?

just had the same situation as you with getting hot while ideling. installed the flowcooler pump in a 340/416 stroker just recently and it dropped my temps down roughly 8-10 degrees while driving and slightly while ideling. this was from an 8 blade pump that was already in it. fit well and looks o.e.m. pretty happy. just my 2 cents.
