Thanks
For economy and reliability build an engine and truck up like mine.

Newer style 6.5L turbo block, small valve heads with small mouth heads (#162 casting),, j-code intake manifold, super sized air cleaner, cold air/ram air intake, foward of the rear axel dump exhaust, electric fans, some DB2 serries mechanical injector pump.
Dont bother with the electric coolant pump I still consider it in the expermential stages.
I don't have the 5-speed but it would be nice.
If I were staying N/A I would put on some long tube headers, maybe straight pipes too.

Water injection may help under load, I am getting set up to test N/A water injection. Since its winter it will likely be watered down methanol mix.
