What are the advantages of the 5.9 vs the 6.7? And vice versa? I'm wantin to buy a diesel but the damn 5.9 03-07 four doors are damn near impossible to find. So looking at 6.7s just to see what they are about. Any body got the pros and cons?

 

6.7 and deletes. Be happy

 

6.7 are a power house for sure! Delete it and you are basically good to go. The only downfall from there is the trans (If auto) Although the stock transmissions are a weak point on the 5.9 as well.

Either way you cannot go wrong!

 

The g56. Is junk much over stock hp in my opinion. I have trashed 2 g56 cases. ( no racing at all) And I'm only around 550ish. So I done a 5600 swap and put the g56 in my 12v.
