Wondering What The Dwell Setting Should Be For My 1970 Coupe Deville 472ci?

30 degrees.

Thanks For The Respond, Now There Is Just One More Thing...on My Timing Marks There Are Three Marks In A Line From Left To Right 1...2...3. Which Mark Is 0 Tdc, 1st , 2nd Or 3rd Mark?

The pulley turns clockwise when you look at it from the front, right? If so, I guess 0* would be the farthest clockwise. On mine, the marks are 0-5-10, and I set the timing to 5, the middle one. I am guessing you would want to aim for the middle one too. I think your timing is supposed to be 8* BTDC? So maybe your 3 marks are 0-8-16?

Ya Thats What I Did Except I Set It At 7.5 Btdc, Seems To Be Running Fine Now. Thanks For The Help. Now Im Just Not Sure Wether Its A 472ci Or A 500ci, Need To Check My Numbers.
