4.10 gears
What guys are running 4.10 gears with 383, and how do you like them for street use? I am running a new 383 with miniram and wanted to get a bit more low end punch as i still have stock 3.33 in my 89 6 speed. i am after both positive comments and if any negatives about them, also what the best brand ,Gm or other. Car is daily driver with occasional track days. 
Thanks

4.10 gears
If I were you I would visit the track again and see which gear you finish the 1/4 mile. I have a stock '94, with 3.45 gears, and believe it or not the car had to be shifted to sixth gear at the end. Im sure that the 383 is a faster reving motor that the stock L98, so one more visit to the track would give you a better assessment on going to a deeper gear. Good luck!

I have a 383 with a miniram and 4.11s. I am in 4th gear at 6200 rpm as I cross through the traps. I like the 4.11s alot. I've got 315's on the rear which helps with traction. It also makes 6th gear much more useable.

I'm in the same baot. 91' 379ci 6 speed, 3.33 gears. My engine pulls like no tomorrow through 8000rpm 
. I was thinking of getting 3.73's or 4.11's to better suit my tunnel ram 
. I was going to wait to decide until I get the new motor to the track and see what gear and rpm I am going through the traps. But any experiences would be helpful...
I hear Toms diff have good gears and also the 4.11 from the Dodge Vipers work as well...

thanks all,
I don't go to the track more than 6 times a year so having a more usable 6th gear for the street sounds good, anyone know what rpm 4.10's run at in 6th gear on the freeway?

4:10's has been recommended by several members of this site. It was recommended to me as the first mod I should do. I have a friend that has a 01 Camaro SS with 4:10's as his only mod and it made a big difference on the butt dyno. He is revving at 2200rpm at 75mph and 6th gear feels more like that of the Z06. I haven't done mine yet, but will get it done over the winter peroid.
