I have a 1977 440 block. The casting is 4006630-440-1.
From what I understand, this block is a "special" block, most likely from a police car...
i need help figuring out what heads i need. i will include a pic of the block...so ANY info regarding these heads and what type i need would be absolutely fantastic!!!
