Water Pump

I got the Edelbrock pump the reason I bought it was because they claim it flows each cylinder head equally and flows 40-50% better than stock. Not sure what the other ones claim but want to check it out.

With your heads and supercharger I'd get a good quality pump.

I'd have to agree with TrophyHead about going with a quality pump. The last thing you want is to crack or warp a head because of insufficient water flow . The edelbrock pump is the way to go in my opinion. I researched for quite a while to see if it was really worth the extra money, and in my opinion it is.
