So I k ks there are 2 different 6.4s that can be bought. The 1 out of the truck with 410hp and the srt8 version with 485hp. My question is can I buy the 485hp long block and swap my stuff onto it, tune the computer and go?

1 person has mention i would need to switch out some wheel inside the motor that the computer reads in order to do thi . Does anyone know if this is true?
