Just me, but I prefered Archies original belt driven pump. Everyone I know that dont just drag race their cars always seem to have issues. Belt driven ones have been around 100 years now and seem to work just fine. Just my 2 cents.
I ran Archies mechanical pump for about 10 years on my ZZ3 SBC and went to a CSR about 5 years ago - no problems with either one. I went to the electric pump basically for aesthetics and the fact there are fewer moving parts to break. I recently switched my old ZZ3 SBC for a new Ramjet 350 crate motor and I'm pulling the engine one more time for final fitting this week and I'm thinking of upgrading the CSR pump (or maybe just replacing) as preventative maintenance and I'm curious which electric pump the guys prefer these days.
I have a CSR electric pump on my sbc for 7 years with no problems. Like you said I like it because of less moving parts. I brought a extra elictric motor for mine just in case I ever need it.
Good idea! I like the idea of just carrying an extra motor for the CSR - doesn't take up much room. Actually, I haven't heard of one going bad yet so the advertised MTBF must be a pretty good number.

According to the CSR website, they recommend the motor be replaced every 3500 hours or 50,000 miles of everyday use. They also state the water pump should not be run on a closed thermostat. If that is the case, do you need to wire the water pump motor thru a thermal switch that closes at a temperature above when the thermostat opens? How are you guys running electric pumps doing this? I'm interested because I am planning a V8 swap soon. Thanks.

i have a CSR water pump, i dont run a thermostat but i have a restrictor plate in place of a thermostat, if you want to run a thermostat you could drill a couple of small bleed holes in the thermostat that would allow some slight flow of water, maybe that would work as well.

Not sure I have this fact straight, but from what I recall in talking with Archie, he seamed to indicate that the when the thermostat is in place (in his custom housing), it may have a few MM of travel (up/down). I think this was done so that when you are getting the air out of the coolant system, you can add water from a hose and the air will push the thermostate up and "burp" out. Does this make sence. At least this is how I understood it. So in the case where you mentioned that you should not run an electric wp with a closed thermostat, this movement would allow a small amount of water to move through the system before the heat opened the spring. Again, not 100% sure this is true.
