Water pump for LS3
 

I'm trying to unclutter as much of the engine bay in my current build as possible. I'm running the usual LS3 and only accessories I'm going to be running of the crank are the alternator and the water pump. I just don't like how the stock pump looks. Do I have any after alternatives?

Besides going to a billet electric pump, I've seen adapters that allow a big block Chevy pump to be installed on an LS.

I found a billet water pump for the LS that moves the thermostat to the top, but it's quite pricy. Comes in black or silver.

Thanks Jody! The one in the pic looks like something I could use. How much is it and where can I learn more about it?

I'll tell how Im doing this, for another reaaons but kind of same thing.

I need to loose the stock water pump. Dont have room for it. So I machined boltable blocking plate and I will machine "tower" for guide pulley to be bolted, welded or threaded when I know where and how long. So I can play with belt rounting.

I saw this billet piece for the guys who run remote electric pumps.

Again easy with LS, aftermarket support is huge.

Had to make it yourself.. still need to countersink all the bolts.

Totally agree, good job!

That's an idea. I used this: https://www.vpw.com.au/parts/DC-8025 with on of my earlier builds and it worked great with a big cube sb. I kind of did the same as you are doing. I just half-assed it and made a empty dummy wp in stock location just for the pulley to stay in right place. But with this build I just want to make the front of the engine as clean as possible. Small, low mount alternator and idler pulley would be the ideal amount of accessories running of the crank for this. I'm using electric steering column with tilt and no A/C.

Thanks. That looks better than stock and with the clockwise rotation I would be able to mount the alternator when I wanted it in the first place. And the heater out/inlets are in a better place than stock for my build. Still it is kind of bulky piece overall...
