    Curious how you'll are running your pcv setup. Or just using 2 breathers?

    My sbc has a breather on one valve cover and just a pcv not going anywhere because I have nowhere to route it to. The only port on the carb goes to the brake booster

    Smokes like crazy through the breather and after some hard driving starts to leak.

    should I get a catch can? I just want it be right. Thanks

    The one on back of intake? I think I'd have to add another carb adapter to fit? How about the carb? Which port would I hook it up to The top or bottom? Or would it not work that way?

    Thanks

    I run an air/oil separator in my PCV line. Made a huge difference in exhaust smell and under hood cleanliness.

    I have it plumbed into the nipple under the secondary bowl, and my brake booster draws from the port on the intake for cylinder #8. I run a 1" carb spacer so a 90° elbow does the trick

    Hmm any pics of the setup with air cleaner off? Seems to have worked for you. Have a breather on the other side? Also a link for the part?

    Thanks

    I used this one from Moroso and I'm quite happy with it.

    Don't have any pics at the moment of the back side of the carb - sorry, but I ran the elbow in where the pipe plug is under your rear accelerator pump.
    Yes, I'm running a breather on the other side valve cover.

    You use the 90* edelbrock elbow right here?

    Looking at the pic don't think I'll need another carb adapter?

    You don't get no oil coming out of vent or smoke from breather?

    Air Oil Separator with a PCV is a good way to go.
    A straight breather just doesn't provide enough evac. The AOS will keep oil out of the intake tract, which is a good thing on many levels.
    I like that Moroso piece

    Take the plug out of the back of the intake, install a nipple that's on a 90* Or a "street elbow" brass fitting and a regular nipple on that. Should not have to use another carb spacer.
