PCV valve ( positive crankcase ventilation) does that without a catch can . With a catch can you need to make sure the can is well maintained as a blocked can can pressurize crankcase on some engines . All this catch can talk got me ordering one todayYou want to vent the pressure that gets past your rings especially on a supercharged engine. It's not just about keeping oil out of the intake tract.

Mags1- where did you get those fenders?I’m NA but I run the Ford Performance catch can. Not sure if it fits with the Whipple or not.
That’s a GTD in my profile pic. Just wishful thinking on my part LOL. I believe someone has come out with aftermarket GTD style fenders, will see if I can find the link.Mags1- where did you get those fenders?
Unless the factory PCV has a check valve, then it only opens under vacuum and not boost.PCV valve ( positive crankcase ventilation) does that without a catch can .

What year 5.0L?So I'm about to put my car down for the winter again and I'll be doing some more work to the engine. Right now it's Whipple Supercharged with several supporting mods. It makes 768WH and I'm looking at adding a good catch can. What ones work best for supercharged cars?
