I have a 4.7 in a 2011 ram. From a dead stop if you floor it is slow to accelerate until you get to about 3000 3500 RPMs then it really picks up speed. I have a 2000 ram with a 5.9 in it and it has way better take off than the 4.7 but not as much in the upper RPM range. Also when it is cold it has a clicking sound until it gets warm. is it normal for these overhead cam engines to have a tick in the valve train.
