Still trying to sort through my high temps. Running around during 100 degree days here with my 440 results in temps pushing 200+. I'm not sure if that's too high, but it begs a question. My radiator is a new 3 core, the electric fan I've got on it does not cover the entire core (maybe 75 percent of it). I know this is a problem and while I await the funds for the mercedes fan and controller, I'd like to fix any other deficient areas. Currently running a 180* thermostat and an edelbrock waterpump (it's what came on the housing when I picked up the engine).

Is this style of pump, with the cast vanes, more or less efficient than the stamped vane mopar style? Should I consider replacing it? Do they become less and less efficient as they age? I'm not sure how old this pump is. I know it's silly to ask, but is that possible?

Thanks for any help
