Have any of you guys swapped a standard Mopar water pump with one of these FK pumps with no other changes? Reason I ask is on my 493" stroker, Glen Ray 22" radiator with shroud, 216 clutch fan, 180* Stant Super Stat. At 80* ambient or cooler it runs 190* all the time. However, with this hot humid weather we have been having it raises temp quickly while idling at stoplights. Wondering if their claim of moving the water faster to drop hot idle problems is true.
