Swapped PCV & gained big time!

[SunSoaked]

Ok, so I've finally got my 350 Vortec running great. The one thing I had been putting off was swapping the Wagner dual stage pcv. Today, I got r done.
With engine warmed up at idle I had 15 inches of vacuum and a very slight lope.
Then I swapped valves and t'd in the purge line from the charcoal cannister.
Started engine and adjusted valve per instructions.
The idle went up 300 rpm. I adjusted it back down.
It idles extremely smooth and I lost the lope I had. It now idles with 19 perfectly steady inches of vacuum and has noticeably better throttle response.
These aren't cheap, but worth every penny IMO.
