Thanks Rusty
We came to the same conclusion over the phone with Comp Cams. The Tech was very informative and helpful. And yes, that middle school kid sound was what I was looking for, knowing it was a marketing ploy of the 70s relative to it sounding hot but actually adding little or nothing to power. We came to the conclusion that the engine compression as built is just too low and cam too much. Hopefully the Tech was not trying to sell me another cam. I was on the right path for my original idea, I just goofed a bit on execution. A swap won't be too much effort as the front of the truck is still disassembled. I just had the radiator setting on the frame rails for startup.
