From my understanding the 6.4 is detuned bc its made to do truck work and last longer. The 6.4 in the srt8 has 470hp so its easily capable of those "paper numbers" if that'll make you happier. Either way even though its only "15 horses" its still a completely different beast. Either truck is ****** awesome though I love both 1500 and 2500. If I towed heavy loads I wouldve loved the CTD but I don't so no need for that monster
