New from TN

Hey guys, i am currently building an 04.5 cummins 3500 nv5600 to replace my 2014 duramax (I'm getting married in December so it needs to go). Any input on the build would be appreciated! I'm looking to make some decent reliable power, i tow heavy occasionally throughout the summer. I just got my block bored .20 over (truck has high miles). I'm planning on going with 125hp injectors and a s467 second gen kit for now, thinking about compounds in the future.
