The water pump pulley is about 6.4" with 1/2" v- belt grooves.
I have the same issues, so I was looking at pulleys also.
The only thing I found was a 3 groove water pump pulley that the two inner groves were the 6.4", but the outer groove was much smaller. But more than likely you are in the first crank groove with your water pump belt so it will not work, all I saw out there.
Only other option would be the hi flow water pump some after market places sell, so I bought one, it did not make any difference, increased traffic through the radiator was not even noticeable at idle.
