I think for the 8.8 rear it is 3.73s and 3.90s. It all depends what you want to do and what kind of driving you are going to be doing the most.

 

[873Stang]

daily driver and strip on sat

 

[dragnazz5.0]

you probably wont even tell a difference between the two, so go 3.90

 

[SuperStang83]

Yeah I would go 3.90

Daily driver though. What are your future plans for the car. How do you normally drive the car? highway or backroads?

With the 3.73's you will be turning 2500 rpm at 75mph and 3000 rpm at 90mph...assuming you have the stock tire size.

The 3.90's will give you about 150-200 rpm higher than that. So you'd be spinning at least 2700 rpm to cruise on the highway. Thats a lot for a daily driver...and the acceleration differences between the two will be almost non-existent.

I would say the 3.73's are the best all around gear...even 3.55's if you drive on the highway a lot.

I agree here

With a 5-speed I would say 3.55s, especially if you're gonna do some HP mods. 3.73s might give you traction issues, and makes 1st gear pretty useless for daily driving.

Just my $0.02.

you can hardly tell the difference between 3.73 and 4.10 in my opinion run th e3.73 they are dirt cheap

what trans you running i have the 2.95 first gear in mine

 

[PUNISHER RACING]

I run 4.30's in my daily with an old school 3.35 first gear T5 I love it my first gear is anything but useless( just ask any stoplight in town)

Ya, I got a w/c T-5 with the 2.95 1st and 3.73's. 1st gear feel like launching an airplane down a runway. Wish I would've went 4.10's.

 

[873Stang]

but if i go 410 what will i be at highway wise like 60mph tops?

 

[ninety1gt]

i have aod with 3.90's , best mod ever!!!! rpm's dont run to high on high way either

 

[PUNISHER RACING]

why would you only be able to do 60? i can run 140 if i want

 

[Mustang5L5]

What other engine mods are you considering to use an x303 cam with??

 

[TRWXXA]

but if i go 410 what will i be at highway wise like 60mph tops?

With 26" tires, about 2150 rpm @ 60 mph. If you step it up to 70 mph, it'll be a little over 2500 rpm. At 80 you'll be at 2875 rpm.

you runnin stock heads, that sounds very familiar to my daily driver stock longblock,with a X cam, roller rockers, headers, Torker 2 intake and a 700 dp Holley with a 3.35 first T5 and 4.30's it is quite possibly the most fun you can have on the way to work
