EGR bypass?

I concur with the fellas.
Once the 4bbl goes on,You will likely be driving it differently, and you will likely drive it less and less in the zone where EGR can be a benefit.
If you up the cam, it will do the EGR thing by itself.
If you up the compression, you won't want EGR in any case.
When things get hot,or the fuel gets stale, EGR can cause problems anyway.There is really no place in a performance engine for a factory EGR system.

On the other hand, if the rest of the engine is stock, and is to remain so, and you spend a lot of time at part throttle and cruizing,AND you have not yet bought a carb and manifold; well then I think I would try to keep it functional, as it can improve low speed-low throttle performance. But it has to be running tip-top.
And/But, I certainly wouldn't replace an already purchased non-EGR pkg.

Thanks for all the advice. I haven't purchased anything yet, but ready to. Just trying to decide if I purchase the EGR intake and the 1400, or the non EGR intake and the 1406. I hear many good things about the 1406 carb, but never anything about the 1400. Maybe it's just not near as commonly used. I would save about $60 on the pair going non EGR intake and the 1406, but at this point doing it right is more important than $60.

I will be upping the cam, nothing to aggressive though. Either a 256/268, lift .447/.455 - Comp cams CCA-20-221-3 or a 262/270, Lift .462/.470. CCA-20-222-3. Plan on an Edelbrock 1720 fuel pump also. Looking at maybe a higher stall converter, possible headers and H pipe, (car has dual now but separate pipes coming off stock manifolds), and eventually 3.55 ratio gears. But one step at a time!! My pocket book has limits.
