    Default Proper PCV Routing Options

    I've got a stock 67' Chevy 2 with the original 283. I've added the Atomic EFI and MSD ignition and was wondering if someone has posted a diagram or directions for optimal PCV? My intake manifold, valve covers and air filter are all Edelbrock. I have the OEM Road Draft tube still mounted with a breather on it, rather than plumbed into the air cleaner housing as was originally done for a California Smog 67' Chevy 2. Not trying to worry about keeping it original, just want to make sure I have sufficient Positive Crankcase Ventilation. I know some ventilation is better than no ventilation and there are a few different ways of doing it. Anyone have any advice or proof of concept, which way is best?Click image for larger version.
