I believe I'm going to go with Holley all the way around. Not that I have anything against Edelbrock. I guess holley tends to make more power, but on the flipside Edelbrock is a better driver and if that's what you're after then by all means I think you made a good choice. There's a guy I work with has a hotrod that he built he uses edelbrock performer intakes, and a 600 edelbrock carb. with a mild cam. He used a th350 and a 3.08 rear end. He's getting 25 mpg. For a 350 without emissions in a car like that I say that's pretty impressive.
