I bought a stage 1 Stewart water pump for my small block. I was shocked when I looked in the top hole, I could see where they drilled it, not all the way but that may be as far as they drill it but there was slag from the milling machine just hanging there. I tapped it with a screwdriver and clumps of slag fell out. May let them have it back! I don't have another pump to go buy so if any of you have a pump lying around please take a look to see if this is the way they drill then. If I keep it I will need to knock as much of that stuff off an possible and flush it.
Damn I get tired of ordering parts and getting the wrong stuff or just plain ****!
