Chaplin,
Drop off on the bottom end? How? At most speeds only the front half of the carb is working and even if it is half the size of the carb that is only a flow rate of 375cfm. So what drop off? Chevy even put the biggest piece of crap ever made on the 350 called the Quadrajet. It ran very small primaries with a manual secondary that was controlled by a air valve plate like the Carter AFB. Granted the nick name they picked up is Quadrabog but that is a case of poor adjustment to the air valve spring rate. Most of them over time got loose so the vale flop open causing the bog problem.
I see by your side bar you have a 427sc ERA. The original 427 came with two Holley 4's that flowed more than enough for the 427 but I do not remember any over carb problems on that engine or the 426 Hemi with two Carters AFB's or the small block Ford with three 2's or the FE with three 2's. All of these were factory Hot Rod engines that had the potential to flow way over there engine size yet all of them were very fast and strong runners for their time.
Sorry my dander gets up on these kind of things and I tend to run on at the keyboard.
