little hole in the head

little hole in the block

Got an electric water pump for this sbc and it doesn't have the passage to match up with the hole on the pass side of the block that allows water to circulate past the thermostat. Is it expected that this hole just gets blocked off? Thanks Curt

[S Did it come with any directions? This is being asked by the guy with ADD that puts it all together first and when it doesn't work I look in the trash for the directions.

Sorry I can't help , Im no mechanic , im more like Kenny C ,, I look for help or directions after it dont work ,, but this will bring it back to the top , maybe some body will help ya out ... Im more of a parts re-placer than a mechanic .. That sucks some times cause I replace more than I need to a lot of times to get it back going ..

All the electric water pumps I've bought just bolt on with no modifications.
Eman, post a pic of the pump.

My experience with electric pumps is limited to race cars... blocked bypass hole and no thermostat, either.

I understand an electric pump moves less volume than the conventional belt-driven type. This may or may not be a concern, but if you run the electric pump, drill three or four 1/8'' holes in your thermostat to "compensate" for the bypass.

You can see it isn't made to cover the bypass hole. The other e-pumps i look at are like this. From what i can google the hole is just blocked and then maybe some holes drilled in the thermostat.

I did not get a response yet from the seller and i want to install it now so it looks like block it up and drill some relief holes in the thermo then.
Thanks y'all.

most of the ProForm SBC pumps have a tab to close off the bypass port, see picture here:

I just realized something. I have never put an electric pump on a small block and big blocks don't have this hole
You can tap the hole with the appropriate size pipe tap and put an allen style plug in it deep enough the top of the plug is flush with the block.

Excellent. I can move ahead with it. Thank you all.
