Today I got to do a full test. The roads dried out, and I made highway and city runs, and also a wot shift from 1st in the city.

Let me first just say....WOW.

Do these gears have a "break in" period? 4th gear on the highway spinning at 3800rpm pulls like a DEMON. I mean hard. 5th gear is around 2600rpm at 70mph, and it pulls a lot harder, pulls like 4th did. No need for downshifting.

As I was in first gear in the town, I let off the gas a little and then punched it again, and broke the tires loose. This put a smile on my face. Finally, the power is showing! Just to make sure this wasnt a fluke, I made sure to get on a very dry road going 100% straight. I floored the car from about 2700rpm in first gear, and OMG! It took off like a ROCKET. I shifted at redline into second, barked the tires, and second pulled as hard as first gear did before. Put a HUGE smile on my face, and TOTALLY took me off gaurd. It pulled soo hard, finally feels like a muscle car. It finally feels faster then my old supercharged Maxima, which makes me very happy. It feels like i've added 50hp and more importantly 50tq to first and second. The pull is incredible, like the hulk rollercoaster at Universal Studios. And yet, first gear is still very useable. The newfound pull put a HUGE smile on my face. Put my car with 3.27's against my car with 4.10's now in this instance, and my car now would pull ahead swiftly and with ease. It feels incredible.

On the highway, I attempted to downshift into 3rd. Not pretty. At 70~ish mph, as I downshifted, the clutch slipped a little, couldnt handle the power. I know on occasion my clutch will slip, but today for the most part it caught. I retract my previous statement about these gears. Sometimes when you mash the gas while in gear, it blunts the feel and some of the performance. Mix that with a clutch that likes to act up from time to time, and it makes for a smooshy, unexciting ride. But today, I got to do some real tests, and it put a huge smile on my face. Definately feels much better than before. Gas mileage hasnt decreased, I am happy with that.

It took some time, and more in depth testing, but I finally got to stretch the legs of my car with the 4.10s. I must say that I am MUCH happier then yesterday, and know that around town my car will pull much harder, and smoke cars that would beat me before.

God bless gears. Ford is retarded for putting the pathetic 3.27's with this jewel of a motor.
 
Glad you are happy with the gears, and yes the 4.10s make the car come alive! As far as break in goes, you are supposed to drive the car for about 20-30 minutes then let it completely cool (like overnight). That is it. I always recommend changing the oil after about 500 miles just to make sure any extra material is removed, then add synthetic and let it ride.

Oh...so the 200 mile break in period is not needed? The guy said go 200 miles and let it run through a couple heat cycles. So I guess I should be alright, since they cooled overnight last nite. I can't help myself from romping on it.

Sig updated. :flag:

ok so you are saying to change your rear end fluid after you install gears?

Craig... I was just wondering if you had the gears installed at Lamotta. I called them last week to schedule an appointment for my gears. They told me about the 200 mile break in period. I'm planning on having 4.30's installed on Saturday. :D

Barked the tires in 2nd gear :shrug: The last time I shifted from 1st to 2nd like that on the street I lit up the tires so bad that I hit the rev limiter and almost went into oncoming traffic! and I have stock gears, wow I can't wait till I get my 3.73's :banana: :banana:
 
What do you guys recommend for my gt auto? i do both hi-way and city driving about the same so there is no difference. I was thinking about getting the 3:73's to keep my speedometer somewhere in the ballpark and because of the freeway driving i have to do, but listening to these stories makes me want some 4:10's!!! Thanks.

get 4.10's and get your speedo corrected with a chip or something...

Huh?

I might also mention that I had my rear end rebuilt at this time as well. The oil was black with metal peices everywhere. I had new axle seals, bearing pack, oil, entire thing cleaned out b4 hand, etc. Runs smooth and dead quiet now.

My clutch is weird. Once in a while it will slip, and others it will catch and hold hard. I figure I better get that vibration problem fixed at least to save the t-o bearing.

TacBear: You have to consider my setup, as well as many factors. I am running Kumho MX 295/35 tires on 10.5" rims. I hook up better then stock, thats for damn sure. Also keep in mind that not always do I cleanly get into the gears. Once in a while, on certain roads, I will just spin. If the road is too smooth or whatever, the car will spin, and if I shift into second, it will twist sideways. Some roads I can just hook up on. I personally like hooking up though. Tire squeeling and all that crap just makes you slower. My car rockets through 1st and 2nd, only spinning away on certain roads, and thats what i'd much rather have.

CyberDavea: Yup, had it done at Lamotta. Friendly people, good prices, and they know what they are doing. I trust them now. TONS of stangs at their shop (like 20) being worked on ranging from cammed 5.0s, to new cobras, to bullits, etc.

And to everyone else, thanks. I cannot wait to add some HP to this combo. I think some Steeda pullies and T/A will compliment the fast revving gears very well.

you gotta remember 3.73's on an auto will feel like 3.55's on a manual, so you want 3.90's, if you want 4.10's on a manual you might wanna look into 4.30's for your auto :)
