There all pretty the the same unless you get an electric w/p. Meziere has a heavy duty version but reqiores some cutting of the passenger side fan shroud.

There is no high-performance, cam-driven water pump per say. As mentioned, the only way to add some hp is to go with the electric version, in which case Meziere or CSR make one. Check out the supporting vendors, several sell them as do Summit and Jegs.

Ok, excellent I checked them both out. I noticed someone stated that i'd have to do some work to the fan shroud in order for the Meziere pump to fit. In your opinion which one is the better of the two? Also what would I hook the pump up to?

As far as wiring, I used the power circuit from the AIR pump (which i had removed), including the fuse and relay, with the relay triggered by the fuel pump circuit (so that it's always running when the engine is).

Be aware electrics free up power by moving A LOT LESS water.
Do not know what your definition of "high performance" is so this is something you should be aware of.
The stock pump is pretty good moves a lot of water with realatively little cavitation at least compared to older designs.

Its up to you, if you want to add a little extra power and don't mind going through the additional steps in installing an electric pump, then it may be for you. Otherwise, just go with another mechanical driven unit and bolt it right up.

I don't know about the whole "electrics move less water" bit but for what its worth I have installed three different electrics on three different motors and none of the three ever overheated due to "less movement of water" if anything they move more water when your sitting still which is when you would want it to be moving. The electrics move the same amount of water weather your sitting still or doing 75 down the freeway. The electrics free up hp by not putting resistance on the engine. as to which electric you go with depends on your pocketbook or you desire to cut platic or aluminum. Meziere has two models for the LT1 the regular model only requires a few cuts on the fan shroud. the hd model requires more removal of the shroud than most people feel comfortable removing. I have done both and unless your going to be running nitrous then go with the standard model.
Good luck
