Hi everyone I'm pretty new to the forum, and I need some help in deciding on a truck. The plan is to have a 600-650 whp daily driver. I'm caught between a job2 6.4 with about 70,000 miles and a job1 6.7 with 110,000 miles. Now my question is what exactly would it take to build a reliable 6.7 with that much power. I'm leaning towards the 6.7 because overall ride comfort and from my understanding you don't have to remove the cab to do turbo work? The 6.7 also gets better mpg? Also one last thing, delete for delete which engine seems to be the most reliable? Sorry for all the questions and if I posted in the wrong section. I'm still pretty green to the diesel world! Any help is appreciated, thanks!
