Does  anyone have experience with electric water pumps for SBC engines?  They 
 are advertised to pump at 35+ GPM and have a service life of 2000-3000  hrs. 
 This is an attractive option, but I'm unsure how they will work for  normal 
street use.  I found one post on the internet where a guy used it  for 
everyday driving and swore by it.  Everyone else uses them for short  duration racing.


Hi Jim - You have several choices of water pumps. As you noted, the  real 
intended usage for most has been drag racing. I have one (A  Meziere HD) on my 
Autocross Camaro. That is a similar usage, short duration.  What I did was to 
start the motor up in the run line and warm it a bit, then  turn on the pump a 
soon as the temp came up. I also had twin electric fans  mounted. I would leave 
the pump on during the run - while the motor was  running, an alternator was 
charging. After finishing my run, I would let the  fans and the pump run. This 
would quickly cool the motor down while waiting for  my next run. I had no 
problems with it. For any application needing more  flow, the Stewart Components 
is the class of the field. Check _www.stewartcomponents.com_
