Thanks for all the great responses. Here’s a little more info:

493 w 12.5-1, Indy -1 heads, Indy single plane, Cam is 268@.050 roller and 1150 Dominator . 5200 8” converter and 4.10 and 295/65 Drag radial. The MSD digital 6 doesn’t have a start retard adjustment , it is supposed to retard timing 20 degrees when the retard function is chosen. It’s either on or off.

I’m seeing pros and cons, and the one pro for sure is that it idles great and very crisp throttle response w locked full timing.

For me the main con is the occasional hard start.

Does anyone have success with the two switch start deal?
How about a higher torque starter? Currently using a summit mopar mini starter
