Intake suggestions

I spoke with the tech line at edelbrock today and they highly suggest the Victor intake because of the cams RPM range. He explained to me that the RPM Air Gap is a very good intake but falls short when the engine is run above 6500 RPM. With the convertor Stall being 4000 he recommends the Victor which is made to handle the RPM range of 3500 - 8000 RPM's. They do not have a carb that he would recommend using and suggested that I find something that was a double pump carb. Spoke to the tech line at Summit and they recommended A quick fuel 850 carb. Is anyone else using a quick fuel carb. How do you like them? Do you think the 850 is enough CFM's? The prices on these carbs are very high so if I go with one of them I want to get it right the first time.
Again thanks for your help
