Gear ratio for ls1 6 speed, whats everyone using

[1969x11]

I'm runnin a 4.11 in mine with a 9''. It has pretty good mileage on the interstate with the t-56, I would'nt go any less than 3.90 , but I'm running a 275/35/20. Ifr your going with a 26'' tall tire, I would'nt go less than 4.11's, that is if your gonna drive it.

I'm running 3.73's in my 12-bolt.

I'm running a 9" with 3.70's and a 26" tire. It's worked great, I have 3500 miles on the car now and really like the way it performs. I haven't been to the strip yet, we'll see how good the Nitto DR's hook and if I wanted a deeper gear, but as of right now, I'm happy with my choice.

First gen - SBC, T56 and 4.11's with 18,500 miles on the car. Love the gearing, but might be looking for better mileage. I just went EFI, so I'm hpoing for 20mpg. If I get it, I'll stay with the 4.11s. If not, then we're looking at a gear change.

Thanks everyone. prodigy had the great deal on the 12 bolt, but decided to pass and go for a little more gear.. Kinda of bad timing right now anyway since the company I work for and the union are talking strike in 6 weeks.
