Nah you want 4:10's my 6.2 has 3:73's and I would kill to have ordered it with 4:10's but communist motors limited me to 3:73's when I ordered it. Mine needs just a little bit extra gear to keep it from lugging in 6th gear from 65 and under MPH

At around 65 and under in 6th you can hear it lugging especially on the smallest of grade you can watch the tach and hear the lug coincide with the pcm modulating the converter slip speed since they never seem to ever 100% lock the TCC in cruise mode. I have 3:73's and can only imagine how bad it would suck with 3:42 down gears.
