Gear ratios and driveability

I grew up with a 72 chevelle that my dad bought new. It had the Buick/Olds/Pontiac 10 bolt rear end that had 2.56 gears. And I put 15" Corvette wheels on it. It was cool, but couldn't get out of it's own way!
I really like the 3.91s!

our dart with 2:94 gears and 26" tires pulls real strong down low and can cruise the highway with ease at 80mph..:)
