53Chevy5, I think that the W block is fantastic, and I think once you get past this water pump problem it's going to be super cool. I looked back at your edited post, and you say,

I put the original one back in and it pumps more backwards than the other one did in either direction.I'll run it tomorrow and see if it will work ok, if not, i'll figure something out.

I think that running your pump backwards you'll see about 50% flow, or maybe even less depending on the impeller design? I believe the answer is to either re-route your belt to spin your pump CW, or spring for the high-zoot Billet Specialties pump.

Keep pluggin', you'll get there!
