What gears would the LS6 cam with 100 shot of n2o work best with? 3.73 or 4.11's? This is in an 02 Camaro M6 daily driver.

For 3.42 geared cars NA you wont see anything more than 5400RPM. So you want to maximise your TQ over the 2500-5600RPM band, ie., the STOCK power band. CAMS that peak beyond that will slow you down, even though they will make great peak power.
A proper spec. CAM of around 212-216 duration should outperform a 224+ cam on 3.42 gears at the track. Note the keyword PROPER. Increase the final drive ratio to something 3.91 or 4.11 and its a different story. But then you start sacrificing streeability for track cred. as it will be spin city with anything like spirited driving.
People will have their own opinions here and are welcome to respond.
