[DeTomaso] water pump recommendations

[Curt Hall]

I have one of the Flow Cooler water pumps BRA-1648 for my 351C. Summit Racing sells for $89.88. They say it flow 30% more at low RPM. Been to Vegas the three years with no heating problems! 
   
  Good Luck

>>>Me too. A good 351C water pump will feature a Boss 302-style impeller 
with a plate on the back side, which goes a long way towards preventing 
cavitation of the pump. The one on my car came from Dennis Quella, and is based on a 
Weiand pump body. The impeller has the plate riveted to the back side. 
Jack has said that the Weiand 351C pump does away with the bypass warm-up 
circuit, which would theoretically allow you to run a standard 351W thermostat 
instead of a 351C unit, but I haven't actually confirmed that. I think they cost 
about $170 or so.

Larry Stock sells various made-in-China heavy-duty 351C pumps with proper 
impellers. The castings have much more reinforcement than a standard pump, and 
would appear to be stronger, although you always gotta wonder about stuff from 
China. They are substantially cheaper, just over $100 if memory serves.

Edelbrock water pumps are widely acknowledged as being among the best around. 
Instead of thin, cheap, stamped-steel impellers, they use one-piece cast 
impellers with an integral plate. Summit sells them for $165.

>>>The Boss 302 used a standard iron pump housing, with the aforementioned 
special impeller design, and those work well too. I don't know if the Boss 351 
used the same design, and in any case, a genuine Boss water pump would 
probably be both hard to find and quite expensive. If you're replacing your pump, 
you're pretty much confined to three choices--rebuilt stock cast-iron junk 
from the auto parts store, offshore aluminum, or high-quality (and expensive) 
made-in-USA.

You can spend a bunch more money on a water pump if it's polished, but who 
needs a polished water pump on a Pantera? I'd seriously consider one of the 
less-expensive, high-quality alternatives above....
