4.10s? vs. 3.73s?

89fast5oh · 11-29-2003, 06:26 PM

With a 3100lbs stick car with a 351w making 450 ft-lbs and running ET Streets or McCreary tires, what gears would be better, 4.10s, 3.73s? I have 3.55s and the car doesn't rev as fast as it should. Anyone have any suggestions for what gear i should run???

If its not a daily or doesnt see the highway go 4:10s with some new axles but 3:73's rev pretty fast and still very streetable. If you just want to rev faster and just race go 4:10s

I'm running a pure street car and I have 3.73's and if I had to choose again, I would have gone 4.10 instead. The 3.73's rev fast but just not fast enough so go 4.10. I still get 22.5 mpg with an AOD, 3.73's and a carb so I doubt 4.10's will affect the streetability that much more.
