I just removed the smog stuff (pump, all the stuff on the balance tube, air galley and replace the exhaust manifold with headers) on a stock '70 S30 motor.

Do I need to change any of the settings on the carb or timing after eliminating the smog stuff?

It's not required, but most recommend dialing in more timing advance if you haven't already.

Thanks Arne. Yup, the timing is already advanced.
