    C3 Water Pump Date Codes

    Hmmm...some of the suppliers are claiming they can provide "date-coded" water pumps for my '72. My '70-72 TIM/JG says nothing about date coding of water pumps. Did the original pumps have date codes cast or stamped into them?

    1972 Corvette water pumps were dated coded for both small block and big block pumps. However, the dates are usually not visible when the pump is installed on the car with pullies also installed. So, I don't think that they're judged.

      Kevin: The water pumps are indeed dated, they are partially visible, but not easily readable because of pully interference. The casting date is the same format as the block configuration is.
