I'm considering putting on an electric water pump, any feedback good or bad, any advise you might have would be great. Thanks in advance.

The electric pump should usually only be used in a race oriented or weekend drive scenario. The benefit of an electric pump is that it can pump large amounts of water at any rpm, where a standard pump falls short at low rpm. A mechanical pump is recommended for all uses, especially street, since it is able to pump varied with rpm. It does not flow a lot of water at idle, but it can start out-flowing electric pumps by 2500-4000 rpm, all the way to high rpm. For this reason, mechanical pumps are used in most long duration high rpm racing cars.

Ya, what Ray said. Elecs are good for 1/4 mile because they don;'t pump as much water at high RPM, which free's up some HP. BUt, if you were to run at sustained high RPM for long periods, the flow would not be adequate for cooling and would overheat. the 8-13seconds on the strip is nothing.

Ditto

If you were going to do more than drag race I would recommend a mechanical pump

I have an electric on mine, never have had a problem with it.

Correct me if i'm wrong, but the water pump on the LT1's was cam driven. Going electric is one less added accessory to drive, thus freeing up a little power (not a lot to notice, but every little bit will help). Just my .02

LT1;s water pump is one of the efficient models, being cam driven. There is alot less friction losses turning the cam chain than there is a fan belt. Most lilely not much, if any HP gain there. See, it takes X HP tp move a cetian amount of water. Be it mechanical, or electrical means. Running a elec pump, where deos the electricity come from? The Alternator, which is driven by the engine. In older, belt driven water pumps, there is alot of friction losses in the belt, as well as pumping efficiency losses due to casting tolerances etc.

Well I have been educated now.

I have an electric water pump mounted where the battery used to be. I removed the back freeze plugs from the heads and put fittings to connect hoes to .Then modified the timing cover to have a thermostat housing and temp sensor..................so now this is engine reverse cooled. I went to electric fans as well........... never gets above 192 degrees.

I've been running an electric pump on my bird for 3 years with no problems. There have been dyno tests that confirm a 10 rwhp increase in power. Get an overheat warning light In case the fuse ever happens to pop and your pump stops running.
