Does anyone know the correct water pump for a 67 ss 350? I have found the casting number (3782608) but I'm confused in that some are listed for all small blocks, but the 350ci. Is this because of the year of manufacture only? As long as the casting is correct, will it work? I'm not really as much interested in having the correct date code, I just want to get rid of the bypass fitting. Any insight is appreciated!
