got my 4.10s

[Kaotic_ws6]

i had my 4.10s installed today and its NASTY. im glad i went with them.
i would deff. recommend them to someone with a m6

I'm thinking after H/C of going with 2.73's or so. Nothing like doing 70 in first and covering the 1/4 in 2 or 3 gears. 6th would be useless but who cares, 5th is the new 6th.

[jaslivers]

whats your other mods?

[Kaotic_ws6]

whats your other mods?

open vette filter, throttle body, plugs, wires, stock ported heads, small cam, kooks lt's and y with slp resonater underdrives, elec. water pump stock MAF and intake man. and a daily driver tune.

idk man.. i think that would have a crappy launch??

[jaslivers]

would it make much difference on a lid, exhaust m6?

[blackSS01]

I thought about that too. Lose alot of bottom end. Might be too low, maybe 3.23's or something. Once my H/C is done, not touching it til rebuild time.

what size is your cam?

I think you have your thinking reversed.

4.10s kick ass!! i had my stock rear end still and broke about 4 sets of them when i had my ws6.

Your logic is completely ass backwards. If you have a medium to large size cam, you NEED the steep gears to get you going in 1st,2nd when your larger cam isnt producing the low end torque. Are you M6? Doesnt even matter. Even if your A4, going with anything below 3.73's after heads and cam install is going to make your car feel like a toal slouche. You will need a steeper gear.

Even a stoxk cammed f-body needs a steeper gear IMO. Ecspecially M6 cars. If your M6, dont even look at anything but a 4.10.

not sure, lost the cam card in the move, its not real nasty tho. you can hear it lope but not like crazy

I'm not going with a huge cam. Cam I got picked is 1,800 to 6,400 rpm range. Granted it will take time to get in the power band so to speak, you will stay in the band a greater amount of time. And with less shifts, you would gain time each shift. And with gearing like that, your traction would benefit from not frying the tires at a first gear punch at 30mph. I'm not even close to expert but wouldn't my thinking be correct. If not, I am up for people more versed then me explaining it. I won't be ordering gears for a good amount of time so I have nothing on my hands but time

Is just me or does your power seem a little high with just those mods? You must have one hell of a tuner.....

i thought so too, i was excited whenever i saw the numbers, and the cam might be pretty good size, just the lobe seperation make it not sound super nasty

congrats on the purchase/install

I run 4.10s in my strange dana s60, even with the 4.10 gears I still hold first gear up to 63mph before shifting. (built up valvetrain, rev limiter is set at 7500, car was still making hp too)

however if you have 4.10 gears in a stock 10 bolt, dont be mad or cry when they break. a 7.5" 4.10 gears is made of less material, creates more stress and can not handle the added stress.

if you want the stock rearend and 4.10 to have a chance of survival.
-dont launch on a sticky tire
-dont launch at high rpms
-install lcas

if you do want to chance it and (launch hard)
-weld the axle tubes
-install axle tube to pumpkin braces
-lighten your car a lot...

a lightened car will ran faster and place less loaded stress on the stock rearend.
or do as I did, buy and install a Strange Dana S60... the are bullet proof and if they do break Dana 60 rearend parts are cheap!

Maybe I said it in the wrong text. AAG gets me sometimes. I really think you will be dissapointed going with either two of those two gears choices. What it comes down to is.... lets get into the high horsepower powerband. With the 2.73's it is gonna take longer to get into your cams powerband because your egnines is not revving up as quickly as it could with a steeper gear. What cam are you going with? It seems all cam manufacturs all say ehh.... 2200 to 6600 rpm. Thats what Ive noticed when looking at my cam selections. When you say, "Granted it will take a greater amount of time".... Thats exactly it. The person next to you with the steeper gear will get to their powerband QUICKER. Get it?

Is just me or does your power seem a little high with just those mods? You must have one hell of a tuner.....

I was thinking so also, But the mods list is very vague.

i thought so too, i was excited whenever i saw the numbers, and the cam might be pretty good size, just the lobe seperation make it not sound super nasty

What cam? Did the previos owner even tell you? What was done to the heads? The other mods dont really add HP. Filter, plugs, wires. What TB, What intake? Everyone has a TB and Intake Well, most What do you have?

Yep yep

I have heard the dana 60's be almost overkill. Dont have any experiance besides what I have heard on the e-web. That said, I have also heard and seen once in person... a 12 bolt go down. Sometimes I wish I had a 9' instead of a 12 bolt. But Im by no means a hard core drag racer, so Im very sure my 12 bolt will take just about any beating I personally can throw at it on the street. But the fact is, the 10 bolt will break in your driveway.
