Help me understand my timing please

I'm running the same cam as you in a 402/435 . According to Chrysler, 1-888-528-hemi, my initial should be 15-20, total 32-35.

I'm just getting it on the road after a ton of delays, and I'm running 19 initial and 14 mechanical. Check to see what your msd recommends for your plug gap for 9:1. NGK said for me to use 7938-BKR5E PLUGS.

Starts right up and doesn't kickback, sounds mean.
