422 dyno fail
Possible...... but at the rpm this motor is running, I’d say not that likely.
Whereas, 5500-6000 is the rpm range where the hyd system in the lifters often gives up.
However, without being able to see what’s happening with the air flow through the motor......it’s just speculation.
There may not actually be any valvetrain control issues with this combo.
I’m just seeing the power quickly dropping off, the bsfc numbers climbing pretty high, and the fuel flow in stasis........ and theorizing what might contribute to that.
