Not many cons with the 3.90's w/MN6 cars, unless you are targeting 700-800 rwhp or more. (we put 3.42's in the 1,000 RWHP Z06 we built for top speed capabilities) The final ratio of the MN6 (both 5th & 6th are overdrive) makes the 3.90 wild for acceleration & still reasonable fuel economy at freeway speeds. The 4.10's would be more for a track car that wants to be in the peak power band through most gears, but will be a little high on RPM at 75-80 cruise & fuel economy will suffer a bit more than the 3.90's.
With either, dead stop acceleration will be a traction issue, but practice & the right tires will help. Remember, the stock clutch is only good for only so much abuse.
