going from 2:73 to 3:73...worth it?

I didn't lose nearly as much mpg from changing gears from 3.23's to 4.10's as I did from my cam. And I see all kinds of highway and city driving.

chocotaco...if you're so enriched with common sense, i guess you'd know that a steeper gear in some cases (driver dependent) will BOOST in town mileage. when it's easier for the car to accelerate, less fuel is needed to achieve x speed. you'd also know that an engine with a load on it @ 2,500 is burning more fuel than an engine easily operating at 3,000 rpm. however, you've already absorbed this information from "users and common sense"....but i don't see experience in your crudentials. hmm...that's odd. you're a fountain of information - as long as it has previously been posted on ls1tech, go figure.

EXACTLY!!! I went from 3.08's to 3.42's in my daily driver truck and my fuel mileage improved 17%. My cruising rpm went up from 2100 to 2600. Lower rpm does not = less fuel burned.......better efficiency = less fuel burned. I'm gonna go look for some of that common sense we all seem to be missing........

2.73 gears...fuel mileage...no gains from this, no gains from that... You made me sick just reading your posts! Why the **** did you buy the car in the first place?

if you guys dont think this is right, look at this thread:

why would you buy a catback just to replace it later? makie no sensie
also, when people are doing wheels up runs in the 9s on mildy modified 10 bolts there is no reason to waste 1500 on a used rear end, expecialy when you are arguing about 600. i have a logic book i can send you if you would like

redformulaws6: Yes, I think you would be better off with longtubes and y-pipe (although not slp, pacesetters are a better choice) than 3.73's at this point. Judging by your first post, you're concerned with making et improvements.....then I would suggest that the next thing(s) on your mod list after headers would be 3.73's and sticky tires. 
Chocotaco:
1. This is your first "muscle" car, and first LS1
2. You haven't had it very long
3. You only have a lid, catback and wheels
4. You don't have a cam, heads, headers, a stall or 3:73 gears and it's very apparent by your posts you have little to no experience with any of these mods.
5. Nobody is saying your not trying to help out, but the reason people criticize your posts is because of how adamant you are about mods that you have limited experience with.....mmmmk?
Now everyone play nice, we're all friends here.....well, mostly.

I didn't put 4.10's in my car until after I had gotten a cam, intake, tb, headers, exhaust, and stall.... Just do all that at one time and be done with it!
hello.I have 2.73 in my car and im going to change the m to 3.42 0r 373.I like the 273 for cruising.but dont like the launch or the long as 2nd gear.@ tenths is preety good.wouldnt that be a 2 car lead if say you and another ls1 ran the same time.honestly I dont think nobody got this cars to save gas.
