My 408 stroker had a flowkooler and high flow stat. Never overheated even with sported driving in 102 temps. I had Champion radiator with OE style shroud and mech fan.
Keep in mind that the over or under drive of the pump ( crank to water pump pulley diameters) will have an effect.
OEM spun the pump faster for fewer vanes in the pump. Not sure why?

from what I understand with A/C the pump was driven faster than non A/C for more air/water flow at lower speeds but with that faster ratio the pump would cavitate at high(er) revs so they went to 6 vanes (if I am remembering this correctly) to avoid that. RR
Milodon also has a high flow water pump with a plate on the inside like a flow cooler does. I don’t know about a price comparison. Just another option to check out.
Those type are the best. The water has no escape route, must get captured & pumped through the engine. I have been modifying 'stock' pumps for many years by adding a plate. In every case, the owner reported cooler running after the mod.
You should put one in your toilet to see if it will make it swirl LOL
Cog! Plain belts slip on crap……..
