Which would be best?
3.73s or 4.10s? I have a 94 Z28 with a 6 speed. Can you guys give me some examples of MPH:RPMs? I am keeping this car as a daily driver. When I'm done with the engine I want around 400+hp if that matters in choosing a gear. Thanks-Brad

I know most guys will suggest 4.10s, but I had and would go again with 3.73s myself. I've driven in a 4.10 and 4.56 car and those are a little too much for me.
You can use this tool to check the MPH and RPM for different gears.

I've run both 3.73 & 4.10's . It just depends on your Torque & HP & how much racing your doing. On my last Blown 355 I liked the 3.73 but with my new 385 I'm sticking with the 3.42's. In your HP range I would go with 3.73 for the street. It's really comes down to what you prefer cause there's not a whole lot of difference between the 3.73 & 4.10 when your cruising.

What I mean is if I go with 4.10s is my car going to suck to drive at highway speeds. Is it going to be a huge change from my gears now? I think they are 3.42s, not sure though. I like to drive at high speeds every once in a while and don't want to lose that.

If you like to do high speed runs then stay with the 3.42s.
3.73s and 4.10s are basically a drag race gear, they get you off the line better but limit your top speed.
If it were me I would put 4.10s in a 6 speed maybe even 4.33s but I am a hardcore drag racer so top speed does not concern me.

Sorry if I didn't explain better, I like to go around 90-120 mph if I'm racing someone. Will I be able to do that with 4.10s? -Brad

Yes, you can still do those high speeds with 4.10's, but right off hand I couldnt tell you what RPM's I run at those speeds.

For my application, 4.11s were the best gear for me. my car is a daily driver that goes to the track every now and then and with 4.11s I go through the traps in 4th gear at ~6000rpm.
At 6800rpm, 4th gear maxes out at ~122mph. This is with stock sized tires, atleast in my car.

3.73's are more durable than 4.10's and the stock rear is weak to begin with. I went with 3.73's and am glad that I did. They seem a better all around gear than the 4.10's and with less risk of breakage.
