I just need to suck out more heat.
The cooling runs are longer in the pinz than a volvo.
Anyone every insall an auxiliar pump?
If i did that and mounted a larger fan up next to the radiator, i think id be fine.

Headed down hill, mostly idling, the engine wasn't warm enough to heat the cab.
Seems odd I can't cool enough when under full load and can't keep heat when idling.
Thoughts?

Sounds like a thermostat that doesn't close the bypass passage in the 'wide open' position, unless your whole radiator and lower hose were both scalding hot. Did you test that stat prior to install? How may times has it been overheated? It can harm them. I might be tempted to pull it out and measure protrusion of the blocking side, and maybe pin the thing open and go for a drive.
Seat o the pants dyno rates my belt fan at about -5 HP when it engages...might take a pretty big electric to duplicate.
Not quite an aux pump, but I did install an aux (honda) radiator on the belly of a 309D Mercedes bus i was working on, and it helped.
If you don't have any type of 'lip spoiler' around the bottom of the rad, fab up some ricyness.
Oh, and what is the track recorder there?
