I wonder if I need a high volume water pump. I have ran two different bb's, 440 and 512 in my car and both experienced the normal 180 temp to rise quite a bit past 200 when idling in heavy traffic and uplining at the track. So far no overheating. Temp cools down when revving or getting up to speed. Two different radiators. First stock 3 row 26". Then alu 2 row with bigger tubes. No change. Run stock water pump, 7 blades I think. Tried different fan clutches. 7 blade oem fan, shroud with the fan about in the middle, 1" distance between clutch an radiator. Playing with timing and mixture makes no difference. What do you think? Any prefered pumps? Was looking at Milodon high volume pump with aluminum housing. Any experience with this pump? Thanks Yes. And make sure the pump is turning crank speed or faster.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

I use a 6 cylinder pulley that is smaller in diameter.Stock aluminum housing and pump with a $200 aluminum Afco rad and single Spal pusher fan. It's all in the combo

I've used the Flow-Kooler and Milodon HV water pumps w/ good results. Make you use a high flow/balance flow thermostat like a Robert Shaw.

Really not hurting anything at 200*. My filled 511 would run 218* going down the road and it never hurt anything. I was using Evans coolant and a good oil (Amsoil) at the time. Had Milodon HV water pump and twin electric spal fans. If I stopped, the temp would pull right back down to the 200 range. I removed the electric fans and reinstalled flex fan with shroud and temps would stay in the + or - 200 range depending on air temp. I reinstalled bigger electric spal fans for this next season. Will see how it goes. Yeah, 200* I wouldn't worry about. Put some Evans waterless coolant in there and no worry about boil over til 374* or in our world, never.

What are you guys calling a "high flow" thermostat? Pictures will help Also called balance flow.
