I haven't checked one for years but that don't sound too awful to me.  Is that when you are continuous cranking...like for ten, twenty, thirty seconds or just normal start-up cranking...maybe three or four seconds?

You can make sure the clamps are all clean and tight and that the ground cable is bolted solidly to the engine block.  You know, that's why Ford put the pink wire bypass in from the solenoid to the coil...to ensure good spark for cold starting when the battery voltage pulled down to +- 9V.

I was reading your post on another forum...you said it was cranking strong...that tells me its not a battery/voltage supply thing....re check the ignition wiring for correctness ...if it checks out good and no start,  replace the distributor and or coil...you want a blue spark at the plugs....my guess, a bad dizzy module....send it back to MSD... I had a similar  problem...they repaired and upgraded mine n/c in one week.... jj

If I put my timing light on the coil wire I get strobe. If I put it on the spark plug wires nothing. Does that sound like the distributor or box?

Bypass the box....jj
