I know that opinions on gears have been debated a lot, but what is the latest thought? 4.10's sound like a good fit, but are 4.30's too aggresive, and besides, are the gains that much more than with the 4.10's.
4.30's

For the longest time, I considered 3.73s vs the 4.10s. After being convinced to go with 4.10s, I made a spreadsheet to illustrate the engine RPMs at different speeds with different gears. Then I started considering 4.30s. You know what? There is NOT that much difference between 4.10s and 4.30s!!! I only went with 4.10s because of sparse posts on 4.30s. It seems everyone who had 4.10s loved them, and people who went with 3.73s were split - half or more wishing they had gone all the way to 4.10s. But feedback with 4.30s on a Mark VIII was harder to come by.
I don't have any regrets with the 4.10s, and I would love to drive a Mark with 4.30s for comparison.

I've got 4.56s and its STILL not too bad on the freeway.Just bad on tires.LOL

Wow! But what is the mileage like with the 4.56's?

RE: 4.30's
It didn't change enough to concern me.I couldnt really do the math cause the Speedo was WAY off.I never put the speedo gear in.The closest speedo gear is one for 3.73s which will get it closer at least.I can fix it perfect with the computer, but I havent put it in yet.

RE: 4.30's
Please, let me know about ANY info on the 4.56's. I have not heard about these in the marks, but am very interested.

RE: 4.30's
There are at least 2-users of this board that have had 4.10's and took them out, saying they were too much. Getting them would really depend on your driving. I drive 20,000-25,000 miles/year on the highway and I more than occassionally cruise at 80-85mph. 4.10's would most likely be too much for me.
I haven't seem anybody that thought 3.73's were too much gear.
A couple of years ago, wasfuzz also put 4.56's is his car just to see what it would run in the quarter..........he quickly changed back to stock

RE: 4.30's
Wouldn't climate be a consideration too? After all, some of us live where it snows in the winter, and the Mark is our only car. I'd love to go with 4.10's, but I can't imagine what trouble they'd be on snow or ice. Does a posi help or hinder on snow and ice? I've heard arguments both ways.

RE: 4.30's
Posi will help keep you from getting stuck in the winter. Some say it can affect handling though, making the rear end more likely to step out around turns. Lockers are bad for that, if they lock up in a turn on ice your back end is going to start sliding. Posi/traction lock wouldn't be as bad, but still something you might want to consider. 4.10's shouldn't make it any better or worse in the winter.

RE: 4.30's
I guess I was thinking that the higher the ratio, the easier it is to spin the tires on a slick road. I realize the traction control might help a bit.
I'm also confused about the difference between "lockers" and "traction lock". What IS the difference?
Might as well get my stupidity out in the open now. ::roll::

To start with, a differential transfers torque from the driveshaft to each axle/wheel. The common 'open' differential refers to the gears being able to transfer torque equally to each wheel, so if one wheel spins, the other wheel is virtually helpless as far as traction goes.
The "traction lock" unit applies torque through a set of conventional clutches - steel plates and friction discs preloaded with a spring. The unit applies torque evenly to both wheels, but in turns or where one wheel's traction is extremely different from the other wheel, the clutches slip enough to equalize the traction or allow one wheel to travel farther as the outside wheel in a turn.

"Lockers" apply to differentials that 'lock in' with a mechanism controlled by the driver. When 'unlocked' one wheel is free to spin independant from the other - as in the common open differential. When 'locked', each wheel rotates the same as the other as power is transferred to both wheels irregardless of traction. Electrical solenoids or pneumatic control are common locking mechanisms.

Extreme abuse in a traction lock unit will burn out the clutches and render it ineffective. Extreme abuse in a locker will probably result in broken parts.
