Exactly what is the difference in weight ,and how much faster is one with the same engine ?

When standing next to each other ,no boost launch ,just feet on the go pedal ,I really like to know if the regular cap is much faster ,and if the engine is notice the exta weight from the 4x4 and extra cap ?

just thinking about what to do next year ,although I never saw a used ,06 or ,07 2500 reg cap 2x4 with a laramie package for sale .

Searching on here, it looks like about 6400 vs 7200, or 800# difference. I saw one post that listed the 4x2 vs 4x4 but everything else the same was 500#, so that sounds about right.
