Bought this for a project Charger and just sold the Charger to a guy in Germany.
Heard it run - sounds mean and runs great.
Not too sure what's inside but you are more that welcome to check it all out.
I know that it was taken .040 over a few years back.
Very difficult to find a 66 440 since it was the first year and most of them were in the 67 models.
