The initial should be 19* @ idle & 34* @ 3100 rpm. The engine runs great but the timing reads 52* @ 3100 rpm. Is this a MSD problem? Wires seem to be connected correctly & like I said the eng. runs great. Appreciate your help. 68 GTX Full street trim, solid lifter cammed. Best 11.34 @ 121 mph. 1.72 60 ft.

I'm not trying to say your light is inaccurate, but MSD states to not use the dial type with their ignitions. Apparently the multiple sparks freaks out the light somehow. Rich H. Esse Quam Videri

I do recall others stating that their dial back lights were hit & miss when using the msd. 68 GTX Full street trim, solid lifter cammed. Best 11.34 @ 121 mph. 1.72 60 ft.

Until I ran across this I had been hooking the mopar ecu up to set the timing then going back to the MSD.

I was using a locked dizzy and my initial advance was about 37�. I don�t know how MSD reads the sigal. That�s why it�s too high. Ask them. BR, Fernando 1973 Brasilian Dart E100, boosted 390"
