Recently I found the stock ventilator assembly and PCV valve and tubing. I have a 58 step van with a 261 and thought it was kismet. I went to install it and the tubing doesn't quite reach the (updraft) manifold inlet/wiper port. I thought about adjusting the bends in the tube and it may reach. My question is should I abandon the tubing and use hose, and does updraft carburation work with stock the PCV system? Thanks in advance for all advice and or suggestions.
