Recurved mine over the weekend. What a difference! My 74 has a later model HEI in it. Takes off like a rocket now!

Keep the shiny side up!

Scott,
basically when you move from 0 to 10 the timing mark moves clockwise (looking at the car from the front, I have the driver seat on the right). Putting the dial back to 0, I see the timing mark 2 degree clockwise from the 0 of the timing tab which is fixed. IMHO it means I'm 2 degrees after TDC. Am I correct?
