Gear wise, what gears do you have now? I'm guessing you want more out of the hole power.
Keep in mind the 4.7L will never come close to the Hemi, its just not that powerful of a motor to begin with. There is a point at which you will get little to no return hp wise on your money.
This is true for the older 4.7 engines but the second generation is considerably stronger. It's close to the first generation of the 5.7 Hemi.
