Thanks for the report, Evan
It sounds like that truck was built by someone who had expertise and $$$.
The best combination for doing/getting a good "resto-mod" to high-power driveability.
I know this thread is not a promotion for your shop, but, it does make it clear that these upgrades/improvements can be successfully done (notice that my purist's inclinations do not keep me from calling the work you have done are indeed upgrades/improvements).
Sadly, most likely, less than 5% of trucks that have undergone ambitious (and, too-often amatuer) "resto-mod" upgrades ever make it safely onto the road (and, those projects leave a lot of unusable and unsavable trucks)?
