What is your goal, power wise?
Do you already have an aftermarket exhaust?
What's your budget?
Are you doing all the mods yourself?

Are you sure it wasn't 420whp? 320 would mean something is off.

The 'best' NA coyote power mods don't really change much for each generation.

Cobra Jet top end (ported if possible)
1 7/8 longtube headers
High octane fuel

For tuning, get whatever your tuner is using.
