Anyone use a flowkooler pump on 440? Can you post your experience at idle, and long highway drives? Did it drop temperatures as advertised? https://www.flowkoolerwaterpumps.com

more info on what is going on. overheating at speed or around town? have you verified the temp? what temp(s)? what schroud/fan/mixture/timing in ballpark? any changes/adjustments immediately preceding the problem onset? less likely: lower hose partly sucking shut/stat not opening all the way. a parts house 8 blader with the anticav plate added behind the vanes works real well (just cut a sheet of sheet metal in half & have your welder tack it behind the vanes). TQ (thermoquad)! EDIT maybe too lean

I put one on my 440 back in 1991- a fresh built motor. It always ran 215 degrees: never overheated, but never ran at thermostatic temp either (180 degrees). A few years laster I swapped it out for a stock 7 blade replacement (cannot recall what prompted me to do so) - no other changes to the cooling system- and from that day forward the car ran at thermostatic temp.

I did try it and found my car ran hot at highway speeds. Too much pressure and it never resolved my low speed issues. I just put factory pump on and changed radiator and drove last night and seemed to work great. I wanted to unstand the success rate with this product. I called the company and still waiting for good discussion why it didn't work in my application. Going for another ride today to see if it works out as planned and will provide aan update. Changes made were: Milodon high flow stat Autozone 8 blade water pump Passenger side water pump housing outlet Dual pass griffin 26 x 17 Shrouded clutch fan EFI fully controlled timing and AFR Solid stainless lower hose To be honest this was the exact setup with minus the pump that that I comparing to Flowkooler. To be clear I changed the radiator and Tryed both pumps. I will chime in again if this didn't resolve issue. By the way I just finished a 1000 mile road trip with the flowkooler in this application and it ran 215 on the highway with the occasional manipulation of throttle to cool down. Let off and let some air cool the engine and reduce the RPM.

If I read this right, the radiator was changed also. Just me I think that is what made the difference on the highway temp. too much water pressure/flow would not be a problem tho there could be cavitation at the vanes.

One more... my theory is the pump generates so much pressure that it was fighting control with the thermostat. Another theory to toss around; '68-earlier BB water pump housings are different for A/C and non-A/C installations. I believe the cavity behind the water pump is the difference and might be at the core of some temperature-related problems. IOW, pump vane/housing incompatibility. Since the casting numbers of both appear to be the same, I don't know how to compare the two.

John you're the man (as always). I have a 451 in the works after being on SB's for decades & I have several BB pump housings & I will for sure note to check vane to housing clearance (want .040") when I get to that point.

looks like there might be a ton of space in between there!

It may be (& likely is) a high flow pump with the best shaped & the most vanes but clearances have to be at ~.040" max to reduce what the engineers call parasitic recirculation. not sure if the clearance issue is on the pump or the housing or both or whether milling the housing face or moving the vanes rearward on the shaft (or both) is the answer. I know I got some work ahead of me on my 440 source alum blem pump. I'm gonna have go in the side & hog it out. I'm OK with that & that's why I bought it. EDIT pump housing I meant to say

What I ended up doing on my last engine (475" Hemi), I took that High Flow and had a friend weld extra lengths to the vanes, then blued, fit, grind, repeat, without a gasket till the vanes just touched, then assembled with I think a .015" gasket. And yes I pondered heat expansion.
Haven't gone back in to see how things are going. 4500 miles later and temp gauge says we're still good to go.
Thought about a puller to move the vanes the roughly .200" needed, but went this route kinda just to see if it could be done.
I had some more aggressive vane ideas but went with the simple first and see how well it works and lasts. An experiment I guess.

The 1st flowkooler I bought about 4 years ago did not have that huge gap, and it had way more vanes. With the gasket it was like 1/8" or less. This was in a mancini housing, 440.
I remember when I bought it I had to call them first because they had 2 part numbers on their website for BBM pumps, and I was confused on which one to order. Turns out they were changing part numbers. So, I think at the time I called they were phasing out the old design (probably from complaints related to the issues with the above posts) and that is why they had 2 part numbers. Now all the old are gone, and its just the new design that sits lower in the housing, with more vanes, possibly a different vane shape as well.
