gear ratios and torque

bottom line here is, a 4.10 gear won't make a stock 318 faster, just makes it done quicker. much quicker
yes! that's all Im asking. for the sake of argument, hypothetical, everything being equal, no variables, same rpm, same car, same size tires, same everything. is there much of difference between a ring and pinion of 3:23 ratio and 8 3/4 diameter vs a ring and pinion of 3:55 ratio and 8 3/4 diameter? for rusty's benefit...the reason I need to know this information is whether to change my 3:23's to 3:55's. I happen to like to know how things work, the physics behind how they work, what might improve or detract from the results of how they work. ( things that keep me up at night...how do bees fly without wings with built in lift?) I like quantifiable information vs anecdotal. My apologies for over complicating things.
