Re: 75 Dually build

Day two update. So I did not change the pump out. I called a good friend of mine who is a Cummins expert and he came over this afternoon. We wheeled the truck outside and then started working on the timing and some smaller tuning items. In the end he felt the original pump was perfect and made great power, so pump number 2 goes on the shelf for now.

All the smoke was just the assembly lube and once we got it hot and let it run for a while the smoke cleared up, and after we played with the timing a bit that motor really started to impress us. Great response time and no turbo lag. Can't ask for better than that!

I need to button the front end back up, and get some other small items finished. Then I finally get to go for my first test drive! Been a while since this girl has been on the road...

Kinda nice to see it go from that first time I brought her home to this stage, but don't worry I have some cool plans for LST! OH YEAH!!!

Stay tuned!
