    Are you going to add baffles?
    If not... You will want an oil separator tank like Lowend mentioned.

    I've got 12' length of 10 AN Russell twist lock hose and 10 AN fittings

    I want to build a Blowdown /puke tank that's NHRA legal . I've seen alot of these tanks located in the trunk behind the rear tires

    Can't run baffles due to interference with Roller rockers

    Yes, it can be done, I made many of them, made them for mine, I even have a full stud girdle. I also incorporate a full functional PCV valve.

    That's the idea, but you really want to run a PCV and use the vacuum to pull gases out and recirculating, instead of venting to the atmosphere. The Air Oil Separator removes the oil vapor from the line before it returns to the system. A vent lets the gases out, a PCV extracts them.

    This is what I'm currently running for breathers on both valve covers with no issues or complaints

    Here's a 572 Hemi build I was part of. Part of the testing was just this, how to effectively get a CV setup to work. Customer did not want to smell "oil or engine" fumes in the interior, and since he had big coin in the car and all painted under the engine bay, and good coin in the engine, no leaks wanted or allowed !!!

    Lot's of cubes and crankcase pressure to say the least, we used these Moroso breathers/separators on both valve covers that connected and T'd to the rear of the Mopar in line mid rise TR. We also used clear tubing to "see & track" what was being pulled through. We made 17" at idle, and .9" at WOT, those breathers worked as planned.

    Look at the high HP per cubic inch builds, like EMC....there's CV and PCV setup's of all styles, there's a reason for it....
