I need more timing adjustment

Using the mopar electronic dizzy with the orange box I went from around 15mpg with my '66 cuda (360 4bbl with 2.91 gears) now I get easily 18-19mpg. Don't know much about the pertronix kit, it seemed a little complicated. I wanted to be able to get parts easily if it ever broke down so went with the Mopar kit which is basically just the 70's stock dizzy set up.


Carter better in my op.
