PCV Valve, to connect or not?

First off, those are a pair of cute future Mopar drivers you have Adam R.

Excellent information. Last year my brother was getting his 360 Dart dyno'ed on a chassis dyno. Every time the engine hit 5000 RPM the shop was filled with smoke. The owner of the dyno had suggested hooking up the PCV, but that did not happen. No problems could be found, and the engine subsequently passed a comp check and leak down with flying colors. No smoke while the engine was unloaded at 5000 RPM. I have since wondered if not having the PCV connected was the causal factor for the smoke!

Thanks to all for the input!
