Well,let's do some math..... The 3.27,in 5th would equal out to a 2.19 gear. 3.73 would equal to a 2.49, and the 4.10 would be a 2.74 in 5th,5th gear being .67. The 4.6 most likely won't pull a ratio of 2.19 or 2.49 to Red Line RPM,with windspeed drag. Most likely the 4.10 would have the better chance.
