Pastry Chef is correct, and you won't find much love for those E carbs. They work okay in near stock applications and that's about it. It's basically a copied AFB with parts that don't interchange.
For any kind of performance work you'll need to get into tuning the air bleeds, most likely idle feed restrictors as well as the main circuit, and the transition from idle to main is important from a drivability standpoints with larger camshafts, that's just part of the deal, and those E carbs are a pain in the butt when it comes to that. Much better off with a Q-jet or a Holley if you want to get intimate with the carb.
If I can make a 254 @ .050 cam in a little 302 drive like a dream, and my wife can drive the car daily, then certainly you can make a 227 @ .050 cam work in a much larger 400.
