1969 COPO 427 engine
I am currently looking at a 1969 COPO engine and I need help with some information. First is it possible to have a block cast date of January, head cast date of March, and an intake cast date of March, but the build date be April? It is a 512 block with an MQ code. What else should I look for to verify it's authenticity? Please help me with any info you can give me.
