If you were only getting 12 mpg before you had a problem--if only 6 now you have a bigger problem--Is your carb a Holley or Demon?

If you want to put a smile on your face, put a holley 3310 on it but reduce the primarys to #70s.

You are jetted way too rich for a 780 carb---
What dist do you have?
