71 mustang
 

I was wondering what gear I should put in my rear end to make the car quicker? It has a 351 c in it.

What trans do you have. I have a t10 in my fb with 4.11s in the rear

depends on how much you drive it .

Not sure what trany I have...I proly won't drive it a lot it's just a toy.

All I know is it Is the fmx transmission

3.90's are my ideal street/strip gear

Reviving this thread Coz I'm wondering the same thing, I have the same FMX tranni and the same engine. What gears would b best? I plan to drive it like once a week or so. I'm leaning toward 3.90, I know I want it in the 3's

...?

3.73 would be good too
