"Yes BUT the 288 and 327 are so close that, on the idle circuit, they should be using the same settings and running smooth at a warm sitting idle".

NEarly 40 cubic inches difference beween 288 and 327. That's a LOT!!! I would expect significant carb jetting changes for idle AND hi speed regardless of 2 bbl or 4bbl or any kind of carb, idle circuit or hi speed cicuit.

40 cubes is alot of difference, especialy between 288 and 327. If it was 400 and 440 maybe not much carb difference.
