Water pump

First off I just wanted to say that I'm new to the SLC stuff and I have just started planning everything out now to start my budgeting. I see people having to change the water neck on the water pump and had a question. Why not just use the Moroso # 63566 ? It has AN fittings and it rotates.

cheaper and way easier to install.

The Moroso pump puts out 19 gpm which, in my view, is not adequate for more than casual street driving. Indeed, the heavy duty Mezierre pump at 50 gpm may not be adequate for track use (although suitable for drag racing)
