I'll throw out there that your Edelbrock is too much carb. You have the 1405 600cfm compared to the 4548 450 cfm Holley.
I went from a 1405 to a 1404 (500 cfm) on my 360 in my CJ and I saw a lot of the driveability changes you are seeing - including the sound change.
I know your test is limited to what you have (I sold my 1404 years ago or I would offer it to test), but everyone should keep that in mind.
Despite what the carb companies tell you, there is such a thing as too much carb - for the street anyway.
The felxability in the tuneability on the Holley vs Edl is a fair comparison, no difference in that on from the 1405 and 1404, so that is great to see.
And I will say I am a Edl fan, only because I am familiar with them, but I really like what I see on the Holley, might have to give one a shot sometime.
