Welcome to the board by the way....3:27's are Granny gears!!!
Why? the 4.6's power band is more usefull in the upper RPM range...3:73's OR 4:10's will get you there much quicker. As you gain more experience with the 4.6 you will know that GEARS will be the best bang for the buck, besides supercharging...
Cams are not a bad mod either...not only should you look at the HP gain, look at the operating range / power band at which they generate HP/TORQUE...much different / efficient than stock.
