I have a 96 9c1 with g80 posi, and everything stock on the rear end. My question is what would the big difference be between 3.73's and 4.10's? and what would be the difference for gas consumption?

I went into detail in the differences between gears, just not 4.10's. maybe you could change the numbers to see the differences. http://impalassforum.com/noncgi/ultimatebb.php?ubb=get_topic;f=4;t=007182
