4.10s?

It's not going to help your gas milage if that what your asking. According to this on line RPM calulator you'll be running around 3500 RPM @ 65MPH. I enclosed a link to the calulator.

That calc is trash. Coming from a guy who dives a Mach 1 and has a brother with a Gt with 4:10's: look at it from my perspective. Mach 1- intake, exhaust, chipped/tuned. Gt- stock, with 4,10's. when we Dynoed my car I put down 350/fly 302/floor. After the Gt had swapped his gears not only did he pull next to me (untill he had to shift sooner than I did hehe) but his cruising speed in 5 is awesome. He can use his 5th gear WAY more.. Even around town. On the free way he cruises at 2400-2600 rpms for 70 (in my mach it's 2k even)

With my 4.10's, I'm usually around 2500 at 70 mph. I love having the 4.10's! Depending on your exhaust, it can be kind of loud if it's a long road trip but that's a personal preference. They are a blast to drive around town and I still get 21-22 mpg on the highway.

this is misinfo at it's finest, I run a 275-50-15 tire and switch from 3.73's to 4.10's the rpm change was hardley noticable, I cruise at 2400-2500, These type of responses come from those who read to much on the internet and have little to no first hand experience with such.
