I have LS3/6L80e...... what rear gears to go with?

[81C10LS3]

I have an LS3/6L80e out of a wrecked 2010 Camaro, no cam, no stall, just tuned. My truck(81 c10) will be a DD (only when I'm home from offshore) that sees the strip on occasion. It's halfway done, rolling chassis, starting wiring harness now. Can anyone recommend an optimal gear ratio for the rear end with my setup? I have 3.73 posi now, 29.5" tires...thx

I had 4.56s with my 6 speed before it was fun but too much gear for the trans it wrapped up too fast.I would stay with them 373 they are going to be perfect since the 6 spd has a really low first and second gear

I have 3.42 and really wish I have about a 4.10 or 4.30. But I have a stall too. I would go with a 4.10 if I was you.

Thanks all for the input. I've been reading a lot about the 6L80e low first and second gear and it sounds like 373 is right in the middle for good performance on both top and bottom ends. I'm gonna run these for now and see how she does. Who do you guys like on 4.10posi for a 10bolt?

I'd stay with the 3.73's, but no more than 4.10's. 4.56's are way too much, but of course tire size has to do with it.
