I also noticed a big difference when I went to a big 3/8" fuel log (I don't know why but my car immediately became a lot more responsive). I am running a 427 med riser with a fairly healthy cam and some pretty good bottom end work as well.

ditto on that.....when I built my 351-W for my fastback in the early 90's I used a dual plane Performer mainfold. a few years later I saw Edlebrock came out with the same basic maniold, but had the divider cut down about 1/2 to 3/4 inch..... they claimed at the time, it would equalize the airflow in the intake and make for better and more even performance across the rpm range...
One cold winter day I pulled my intake and went to a buddies shop that had a mill and we cut down the divider by about 3/4 inch, seems my car ran a lot smoother/better at low rpms, couldn't really tell any difference on the top end of the rpm range, but I'm sure it was better........
