EGR bypass

[Alan73Charger]

So my 73 currently has EGR, which leads me to the Edelbrock 1400 carb to sit on the new Edelbrock 3776 intake when I do my upgrades.  I'm concerned with this "fuel economy" carb, especially it only having timed vacuum.  I've been told full vacuum is recommended for the ignition advance.  So if I just bought a 2176 non EGR intake and the 1406 carb what changes would I need to make to bypass the EGR system?   Would it be better to go ahead and get the 3776 EGR intake and just use a block off plate on the EGR?  That way you could always go back to the EGR if you needed too without changing the intake.

I live in Missouri so don't have any smog inspections.

Thanks
Alan

I don't know about the EGR but you don't have to run manifold vacuum for the timing advance. It's good to have the option but you can just try ported or vacuum disconnected and see how it runs. No loss. The 1406 is a good carb, very crisp throttle!

Thanks.  I've heard the same about the 1406, which is why I would like to try to use it if I can over the 1400.  The 1406 is non EGR though.
