For the automatic usually a 3.73 is recommended because of the transmission gearing.

why is it better to go with the 3.73 instead of the 3.91? just asking.. i want to get the best out of my buck.. its my b-day tomorrow so I'm having my wife buy the parts and hopefully pay for the install!!
i know more isn't better I'm just asking what would cons be if i went with the 3.91 vs the 3.73... I'm going with the gm made gear kit so it won't void the warranty.. then go from there with other goodies... I'm beginning to think the problem I'm having is the afm or the injectors.. but i will find out monday for sure.
