140mph faces on original 85mph with 4.10's

[stng87]

i love my 4.10's, wouldnt trade them well maybe for 4.30's but probably not. I have a recently built aod. I was concerned about my gas milage as i am a pussy about losing too much of it, but I cant even see any effect on the gas milage. But in performance, thats a huge difference, even going from the 3.73's. In my experience, 373's are plenty in a 5 speed but I still think that 4.10's feel much better. Youll love it either way you go.
Care about gas milage=3.73's
dont=5.34's no no just joking. 4.10's
Hey anyone running 5.34's is that even a ford gear?
