Hi Lotusboy, nobody has been responding so I will give you all I know, which isn't much. The only electric water pumps I'm familiar with are designed for intermittent use, ie. a drag car. If there are some out there intended for continuos duty I am not familiar with them. The question is why an electric pump? The factory has been driving them with the crankshaft since day one, and it seems to work pretty good. If drag or volume are your concerns, there are high volume low drag pumps available. Take a look at www.speedwaymotors.com for some examples. I believe Edelbrock and Weiand both offer them.
