I recall the old Quadrajet (mostly on GM stuff). With the small primaries and very large secondaries you could FEEL and HEAR those secondaries coming into play.

But, generally speaking and specifically speaking of Holleys you should not be able to feel or hear it very much or at all. It should be a smooth transition, if you can feel it, your secondary spring is likely to light weight. Thus the need for a paper clip test.
