6.0 or 6.4

ive put this on here before but im still confused on which one a 6.0 or 6.4 which one when modded is faster?

The 6.4 has a 346 hp tune practically doubling the stock hp. It will runs low 13's on a tune. It appears to handle a lot more abuse than a 6.0. To make the same power a tuner will give you on a 6.4 you will need at minimun a larger turbo and larger injectors. (Studs and a egr delete should also be factored in).... So basically say a 07 6.0 is 30 grand and a 08 similarly equipped is 36 grand... The 07 would probably eat up the difference vs. The 08 with just a tune (&dpf delete) and the trucks would be some what comparible at the track.
