Does anyone know where I can buy some LS1 water pumps,preferably new,with the flange for a bolt-on pulley?

Evans Cooling has high flow bolt on pulley pumps.

Evans stuff is not cheap by any means. Their product are very well designed.

I had some pump testing done a couple of years ago when designing the coolant holes in the MID sleeves. What we found was the stock LS1, LS6 pump lost almost half the flow to the right bank over 5,000 rpm. The Evans pump has almost equal flow. Also flows a lot more than the stock pump due to it's better impeller and slightly smaller pulley diameter to increase pump speed.

Bearings and shaft on the Evans are premium quality. They are expensive but you get what you pay for.
