4.10......
#11
I got quoted:
$190 for FRPP 4.10's (American Muscle)
$85 bearing kit (from shop)
$35 royal purple gear oil (from shop)
$400 installation charge (evolution performance, Aston, PA)
PLUS
$300+ on a tuner to change the gear ratios as Evolution Performance "is unable to perform that service without a handheld tuner"
$1000+ for gears? Needless to say, I'm holding off...
If you can find a better price, do it.

I just installed 4.10s in my 08 GT manual and I have no complaints. The jump is so much that you'll spin the tires every takeoff but it's enough of a jump to have a blast in when you want. I know the first time I stepped on it after my install I threw my head back into the headrest. Was awesome. Hope I could help.

I thought $400 was a little high. I'd guess Evolution Performance has somewhat of a gear install monopoly on the region. I have no idea.
To the OP, if this is your first "engine" mod, make sure you have at least $1000 budgeted for a gear install just in case things go wrong. I've heard on these forums and from various Mustang aficionado friends that (4.10) gears are one of the most dramatic improvements you can make to a stock (N/A) engine.

However, I would have to STRONGLY advice you to get a cold air intake / tuner combo first. You can find a used one here on the forums for around 400-450$ and it will add easily 25-30 hp at the wheels. Not to mention the tuner can change other things on the cars computer such as throttle lag and the rev limiter. It was my first mod and the best one for sure.

I upgraded from 3.31 to 4.10 last year.
The added acceleration is nice.
As always, don't judge their performance based on the first 5 minutes of driving after a cold start. Our cars drive crappy then because of the computer loopiness.
I can't really comment accurately on the loss in mpg since I have a short commute to work, but I feel as if I've lost about 3 or 4 mpg with the 4.10's. However,....I am getting on it more now that I have the 4.10's, so that's not mpg-friendly.
If I had it to do over again, I'd probably go with 3.73 just because of the highway rpms. I run about 2500 rpm at 70 mph in 5th gear with stock tire height. With 3.31's, it was 1950 rpm.

Something else to consider. I was reading an article last night in the new motortrend that has a quick run down of the 2010 mustang and how they've basically taken the 08 bullitt mods and made it factory on the 2010 GT. The only thing they didn't take were the gears (2010 will still sport 3.31 with 3.73 optional) and the rims (2010 was using 19 vs the 18 on the bullit)
Bullitt was 0.2 quicker 0-60 mph and held that in the 1/4 mile but had a 1mph slower trap than the S197. Meaning, eventually the gear would work against you. 3.73 vs 4.10 I'm assuming you may be 0.1 faster than a stock bullit but probably trap a mph lower than the bullitt. Just throwing out some food for thought.
