I've been running a Weiand aluminum pump for several years and I'm still happy with it.

Re: water pimp (Vetterodder)
That's an OOPS .. ! .. 
. I don't know if I'm being too **** about it but my big concern is the impeller shaft breaking off and making the new DeWitts TOAST .. Thanks for the reply, Vetterodder.

One day at nearly 7K rpm, the front bearing seized. The shaft promptly sheared off. It ruined the shroud and made a hole in the rad the size of a football.
I went with a Stewart pump, as all the local stock cars were using it.
It has huge bearings and the small diameter nose shaft so that I could still use my original clutch fan.
It's been installed for many years with no problems.

...STAY AWAY from gm water pimps (er, ah pumps)...i've gone oh-for-three, small block or big block...i went to weiands and they've been fine...you do not need "racing" or "high volume" pumps for the street - you need the correct volume, not the highest volume
...wher'z a good pimp when you need one?

Re: water pimp (mrg)
I use and sell stock water pimps [pumps], for all environments. Stock low or high HP. However I have seen some totally weird water pump problems on this forum, the likes of which I have never seen from professional installers that perform water pump replacements every day. Personally, I would recommend a stock pump for proper cooling, but to each his own.

Re: water pimp (Ironcross)
OH PUHLEEZE!!!!!
A PROFESSIONAL WATER PUMP INSTALLER???????
assuming one knows the difference between a 1/2" and 9/16" wrench and common sense things like not trying to remove the fan belt with the engine running, EXACTLY what value does a professional bring to changing a water pump that is held in place with 4 bolts through the engine block?
'ZACTLY?
...maybe pimp is the proper word
...somebody's getting ----'d

Re: water pimp (Kid_Again)
There is some truth to that. Sometimes bolts are overtightened or belts are overtightened causing extra stress on the pump/bearing.
I'm not saying you do that!

Re: water pimp (Kid_Again)
Looks like the nod goes to the Weiand pump .. Kid - 3 GM pumps and they all failed .. ?? . . What's up with that .. ? .. You sure wouldn't expect it from GM ..
