Re: Improve mileage 350 with Quadrajet
should be marks on the dampener
look for a grove in it(put small amount of white paint in the grove ez r 2 c)
maybe have a tab off the timing chain cover with a point
some throttle return springs can be lighter ,easier to push,does the gas pedal moves freely too(but must be able to return)
