It says LS1 noob

I have 4.11s, they're not bad. Make sure you don't over gear, or make sure your tire size is big enough otherwise you'll run into bad traction problems or your truck will top out to quickly. It all depends on your powerband, expectations, cam and converter, etc etc.

I have 4:11 with a 30" tall tire. I would put 4:11's in my next truck too. It's great, turns 2350RPM at 70 close to 3k at 80

I also run 4:10's with 30.5" tall wheels. 75mph @ 2400rpm. 4:10's get my vote

Most guys who swap to 3:73 say they don't notice any difference and wish they would have just swaped to 4:10.

If your running a tire taller then around 33 you may wan't to go with a higher gear.

We would also need to know if your on a stock motor with a stock tune or if it's modified?

I had 4.10s but I broke them and went to 3.90s. The 4.10s were great, but I get a few more miles per tank with the 3.90s.
