I am running A 650 double pumper on my 383 in my Charger. The motor has stock heads, stock cam, Hooker headers, and a Edelbrock Performer 383 intake. I am running points, which are adjusted decently.

I am running 67s in the primaries and 70s at most in the secondaries. It feels a bit soft power wise, compaired to how it should feel and the motor is otherwise solid and timing is set ok.

Should I bump jetting up, to say, 70 on the primaries and 75-76 on the secondaries, or am I were I should be?
