I ran into the same problem with my 811 water pump, the #11725 gasket I believe is for the earlier big block short pump even though everything say's it for a later year and the gasket that I found to be the correct one was the #13032 gasket if I remember correctly.
I also replaced it while it was still on the car, a little tight but it can be done.

Exactly! 13032 is listed as a Chevy small block water pump gasket.

Bought two gaskets, just in case.

It's all back together now, just need to burb the cooling system. I'm waiting for my alternator to arrive.

Thanks everyone! [img]<<GRAEMLIN_URL>>/beers.gif[/img]

I found if you drill a 1/8" hole in the thermostat,you will not need to burp the cooling systerm. Hope that helps. Paul
