R&P gears change nothing in throttle response. Throttle response is the time taken from the moment the throttle body is opened to the moment the engine responds, makes torque. Lower gears also don't move the powerband up or down, they just multiply the torque transmitted to the ground, to the tires. The torque number and torque-band applied to the r&p by the engine is the same no matter what gears you have. You will feel a bigger increase in power with lower gears, more acceleration, more pulling power while towing, throughout the whole powerband because of the multiplication of torque to the wheels. It takes a big increase in horsepower and torque to overcome the under-gearing over stock. I think with your setup gnarlly4x, it will pull about the same as stock maybe a little bit more in the lower end, less on the top end because of the characteristics of the cam, and the under-gearing vs torque increase will pretty much match stock performance with stock tires/gears from what I have seen in the past, I've enjoyed reading about your build and I'm anxious to hear your opinion on the outcome and dyno numbers.
