Differential: How does the difference from a 3.08 to 3.42 translation become noticeable?

Hello Leutz, one speaks here and there of blocked and short axles. But how does a 3.42 ratio make itself noticeable if one had a 3.08 in it before? Would one only notice it on the highway or is it already on the 1/4 mile that it is “different”? Or is even the difference from a 3.08 to a 3.42 so small that the conversion is not worth it? Therefore, I would like to have translated my bird a little shorter than the 3.08. riding on a blocked 3.42 makes sense or you would have to go even higher to make a difference on the first meters….
