All V6s except the 2LS have 3.27 gearing.

Actually 278 TQ is not too bad for this engine. Sure, 300 TQ would be nice, but look at many other potent V6s out there and you will find their TQ numbers are quite a bit lower than their HP figure. My numbers aren't exact, but the mustang V6 makes around 273TQ, and even the all mighty 370Z makes no more TQ than our car does. But both of these cars offer lower gearing and weigh less and so their straightline performance is better.
Look at the new Cadillac ATS with the LFX V6. It has the exact same 3.27 gearing, but weighs only about 3460 lbs compared to the Camaro V6 3750 lbs. The ATS is rated at 5.4 seconds 0 - 60 while the Camaro was rated 4 or 5 tenths of a second slower to 60 than that. Put lower gearing or add bolt ons to that ATS and suddenly you could have a V6 that will do the 0 - 60 in under 5 seconds.
