Traction? What tire do you run at the track? I managed OK with my drag radials. You gotta' learn to launch the car with 'em, but when you do, it's great! Even on the street you can get decent traction if you learn to launch it.
Good Luck!
<strong>I went from 11.64@116 to 11.63@118 switching from 3.23s to 4.10s. I also lost about 30 miles to the tank doing mostly highway driving.</strong><hr></blockquote>
Terry what was your 60's, weather, and it was at the same track right <img src="gr_stretch.gif" border="0">

60' with 3.23s (on that run) was 1.72
Same track, same weather, etc. So far I am not impressed with the 4.10s, although they make the car an "animal" on the street. If you go from 3.23 to 4.10s you probably need to add more stall to keep the shift extension. I'm going to try raising my shift points from the current 6400 to 6800 soon. On the dyno I make OK power up to 7000rpm.

Really it makes sense if you are looking to extract every bit of performance out of your car.
Otherwise, don't, gas mileage doing 3000 rpms on the highway all the time really goes down.

<strong>I think I can handle the traction problems with a little something called ET STREETS and a hand full of suspension parts I have picked out. </strong><hr></blockquote>
I hope those suspension parts include a front Hal shock/spring setup because the ET Streets are a joke with my Vig 3200/3.73:1 combo.
IMO, you shouldn't mix 4.10's and daily driver in the same sentence. <img src="gr_stretch.gif" border="0"> 3.73's are definitely the max I would want for a driver. I took a 700 mile trip last week in my SS, and I averaged 22.5 MPG w/ the 3.73's. It's down 2.5-3 MPG from when I had the 3.23's. I would HATE to see it with 4.10's!

lol, you better get some 26x10x15" drag tires, ET streets are NOT going to get it done. <img src="gr_images/icons/wink.gif" border="0">
Regarding street driving with 4.10s, its not that bad. I lost about 30 miles per tank compared to my 3.23 gears (~2mpg, mostly highway driving). I generally do ~75mph on the highway. Also FWIW I just added Hal shocks and drag springs, and as I suspected they are a total waste of money from a 60' point of view. They do help you pull tire easier which is a bit more fun though. <img src="gr_images/icons/wink.gif" border="0">
+car will pull harder in 3rd at the track
+car will pull harder on the highway from a roll
+more optimized for the drag strip
-traction is a joke with stock radials
-more fragile than stock 3.23 gear, more teeth
-need to figure out good shift points with HPP or you will be shifting into OD on the track.
