Looks like my overheating problem maybe related to the pump. Anyone ever have any issues switching to an aluminum water pump? Any considerations when going to an aluminum pump?

Thanks
 
Only advantage I can see to using an aluminum pump is for weight savings. Otherwise I think it's a waste of money
 
Yep, that is my thoughts too. Get a new good quality pump. That is sufficient. The only real advantage of an aluminum pump is weight. My opinion.
 
they dont rust and 440 source has them almost as cheap as steel. milodon moves more water

Cool. If they are around the same money, i say go for it. They are pretty.
 
Moving more water can cause you problems if you don't need to move more. It's possible to circulate the water so fast it doesn't have time to cool off.

just something to consider

What radiator are you running? What makes you think it is the water pump? Just curious. I have seen aluminum radiators do amazing things for hot running big blocks.... Just saying.
 
I am running the 22" radiator. New coolant & t-stat installed. Engine runs about 180 until about 25 mins into a drive and then starts to climb all the way up to about 210.
 
My (ex) Super Bee was a #'s 383 auto car. Still had the 22" radiator in it, although I added a shroud and clutch fan (hard to find one short enough to fit). I ran a 180 thermostat and an "a/c" waterpump and never had any issues with it at all.....even screamin down the highway twistin 3700rpm with the 3.91 gears.

Find what is causing your problem and don't just try to mask it.

I forgot. That 22" had a 3 row core but did NOT have a higher than original fin count. Do NOT run a radiator with a higher than O.E. fin count

So, the higher fin count does not mean more cooling power or surface area for cooling right?
 
not if the air is having a hard time moving thru.
 
If you believe the radiator manufacturers it does mean more surface area (and technically there IS more surface area). Problem is the tighter the fin count, the less air that they seem to pass. All these "new" cars with all the emissions stuff are made to run at a higher temp than our older cars are. So for them the higher fin count is perfect.
 
Could it be possible I have the wrong radiator in the car? Both hose outlets/inlets are on the drivers side....
 
3443952 is listed as a 71 C body 383/440 radiator with auto and heater. Does NOT say w/A/C
