Things I have learned about performance engines and cooling systems are you need a lot of coolant flow and good clean airflow over the largest rad you can fit in the core support. I drive a Flowkooler pump 1-1 with the crank and an ECP 26" aluminum radiator with great results. https://speedcooling.com/product-category/radiators/mopar-radiators/page/2/

Can't disagree with the bolded part But myself I have seen no change with the flow kooler or other similar pumps testing under as close to laboratory conditions as I could get and measuring with thermocouples and digital meters (laboratory grade again)
