I dont think it would be worth it. Not if there is nothing wrong with the 3.42's If you scroll down on this link, you will see where you can put in your tire size, trans gear ratio, and rear axle gear ratio and it will give you your rpm. You can expieriment with the two ratios to see how little of a difference there would be.

THATS ONLY ABOUT 2000 RPM DIFFERANCE @75 MILES AN HOUR. I THINK I WILL STAY WITH MY 3.42.

No problem. Though I think you mean 200 rpm difference
