Sorry but that is backwards. With 4.10's every time the rear wheels turn once the motor turns 4.10 revolutions. Same way with the stockers only then the crank would turn 3.27 times for each turn of the rear wheel. It's like a 10 speed bike. In first gear it;s easier to turn the rear wheel but you can't go as fast as say in 5th gear which is harder to turn but can go faster. With 4.10's the engine can rev easier but your top speed in each gear is less than if it had the 3.27's. mark
