3.73's or 4.10's

Well it's a daily driver with occasional trips down the interstate so I guess I'm leaning towards the 3.73's. The car pulls real nice with my stocker 2.73's so I'm expecting a better pull with the gear swap. With my stock gears I do 2000 at 80 mph. Like a few of you mentioned the 2.95 1st gear tranny has a lower 5th gear ratio so I guess it'll make up for the 3.73's some like some of you mentioned.

Fairly minor difference - .675 5th in the 3.35 first tranny; .625 5th in the 2.95 first tranny. But every little bit helps. I've got the 2.95 1st/.625 5th tranny w/3.73's. However, my tires are a bit shorter than the Stang's so it's like 3.90's in a Stang. Turns over about 2400 rpm at 70mph. Highway mileage remains good however - 24-26 at 65-70 mph.

Well I guess its not that much of a diff but yeah, every bit counts. Im really not too worried about mileage because most of my driving is city...I would say 95% of the time battling traffic.

You may actually see your in town mileage increase a hair as the car won't take as much throttle as it used to in order to get it moving.
Do you recommend a self installation? I've heard of people taking the task and saying it was a breeze but time consuming.

The truth is that done correctly, there's a certain expertise and a number of special tools that are required to set a rear end up. There are a lot of people out there that 'guess' at it, and some get lucky. Others aren't so lucky - from them you'll hear things like "It was a breeze; they whine a little, but it's not bad...." If you've never done it before I would suggest you try it only if you've got a buddy to help you that has the know how and the tools to do it correctly. If that's not available, I'd pay someone that knows what they're doing to do it.
I would love to try it myself but I still need to thinkbout it. Anybody know how much it will drop my time? I've never timed my 1/4 but any guesstimates?

I already posted,,but I didnt see you had a 5spd!! 410's are a little much! 373's in a 5spd are like 410's in an aod,,if that makes sense.
Funny thing.....I was doing a 5-lug conversion today, and look in there, and behold my gears are stamped with FRPP 3.73. LOL. I bought this car in April, and when I bought it I thought it was peppy because of the 5 speed (my first). Then I saw the Door code was 'Z', which means 3.08.....so I was like "Ahhh...thats why." Now I guess they are 3.73's. No wonder 1st only goes to 15 mph.....lol
lol! thats funny! Why didnt that happen to me? grrrr. My car is peppy like you said but except that I could do 50 in 1st. By the way, how was that conversion? did you use drums or swap over to rear disks?
