I will be doing a rebuild on my 6.9 in the coming months. Curious if anyone has done a stage 1 rebuild from R&D and what the results have been?
This is the route I will likely be going. Hp, tq, fuel mileage, which is always difficult because everyone drives differently.
This is going into a 1970 f250 with a zf5 4x4. Stock rear dana 60 with 30 spline and front is a 2003 superduty dana 60
