In the trucks the long water pumps started in 1973. In cars they started in 1969.

As I mentioned, I have spent countless hours and trips to junk yards trying to mix and match in the past. I even put a want to buy ad for anyone that had an untouched short block that would be willing to sell all the parts off of it. No one answered the ad.
