Here's how I did mine. This is on a 59 type block. Essentially, I added a threaded tube to the pan vent area and added a small filter to it. It's located just behind the block drain in the pic. Next, I added a 1 1/2" copper cap to the fuel pump area where the original tube (now removed) is/was located. To that cap, I soldered a barbed hose fitting that then connects to the PCV valve located on the bottom of the manifold with a hose, similar to the way 289V8 did it. My thinking is that the air enters through the filtered tube, moves around the crankcase, picking up blowby gases, then is sucked up through the PCV valve to be burned.
