My engine block has a cast date of A-13-69, heads cast C-28-69 and intake cast 3-27-69, but the engine pad is stamped with a build date of 04-10. What would the cast date ranges be for the exhaust manifolds, distributor, water pump, carb, and fan? I unfortunately do not know the build date of the car itself. Would some of the parts be prior to the build date of the engine and others attached on the assembly line? Is there a time line as to when parts were cast and then assembled onto the engine? Are there any publications available that explain this topic well?
