School Me On Distributor Performance

I'm surprised by the cam comments. It has shorter duration than a factory 340 cam. Plus its designed for fuel injection, so its ground on a 112 LSA. I was expecting the idle to be mild.

Voodoo Hydraulic Roller Cam - Chrysler 273-360 (W/ Long Snout) 264/270
My bad. Somehow I read what you posted as duration at .050
It very well might be OK.
A timing advance curve similar to what used to come on Mopar Performance distributor would be a good starting point.

If you want t o do it all yourself you can use the engine as a distributor machine.
