what is everyone's feeling on these ratios. I've got a 91 lsc and trying to get other views on the gears.
 
??????????

I curious as to what it is you're trying to accomplish.

Daily driver????

Improve gas milage?????

Faster 1/4 mile????

What trade offs are you willing to accept????
 
I'm not sure what I'm trying to accomplish. I like the speed and I like racing but it is my daily driver. I love to mess with the young kids and there mustangs. The kids look at my car and laugh until it rips the tire up because of the stall converter.so with the gears I think it would be that much better. I'm guessing I'm trying to acommplish all that you say.
 
Going by the numbers.

So it's a daily driver, then......any change will have a trade off. Stock is most likely 3.08.

As the ratios go up the gas milage and top speed goes down. Although you'll acheive top speed quicker, the engine will be turning at higher rpm's at normal highway speeds so the gas milage goes down. Therefore, with the price of gas going to go up even more, differential swaps is not the most efficient change.

If it's street squrriels you're interested in hunting, a blower would you better results and even give you better milage (if the added power at the touch of the toes doesn't constantly seduce your ego).

Life has a way of always making the fun stuff have a trade off. Any change in the car will have them, and if your married these changes can have far reaching side costs.

Hope this helps.
 
Another vote for 4.10's; especially if you keep that dreaded AOD transmission.

Not true. Mine went up because the car wasn't lugging around at low RPMs any more.

I've got 4.10's in a box waiting for install and a five speed.

The car is a daily driver and I also live in south jersey, you'll like it. :D

Do it, do it.
 
Well I Piicked Up 410's For The Car . Hopefully In The Next Few Week I Can Put Them In. I'm Missing The Install Kit But I'm Going To Rebuild The Traction Lock With The Kit I've Had For The Past Year. Then I Can Put My Trick Flow Girdle On that Came Off My Mustang That I Just Sold.
