422 dyno fail

Boy, this thread sure went sideways. @Jim Ward what did you learn from all of this? I hope that some of it helped. My 2 cents would be to make any checks outside of the car before installing it. Things like checking cam degree, spark plugs to check for dead cylinders, double check TDC compared to your damper, double check valve lash, perhaps even check the springs that are installed and consider upgrading them if they are not up to the task. I personally would not worry about the cam, (except checking the degree), the headers, the heads for flow. Perhaps others can make some constructive recommendations for how to proceed without starting over.
