I never really figured out the vented vs. non vented cans, I think the vented ones were for any form of forced induction. Naturally aspirated I think you want to stick with non vented.

I have a catch can on my c10 and also on my 14 with a gen 5 5.3. Both of them are Elite Engineering and are non vented, they are really nice but quite expensive new. I did some watching and scored two nice used ones, the one on my c10 was actually for a Camaro, but it worked out really good as I am running a Camaro water pump and included bracket fit in a good spot. I also run a clean side separator on both, its the black filter deal on my valve cover. It helps keep any small amount of oil that can back feed through the clean side of the PCV system out of the intake.

You will have a huge mess if you start the transmission like that, at minimum loop them to just start it. Before you do any significant driving you need to plumb them to a cooler. Whatever you do dont cap them off.
