About to start assembling 350 chev motor for my T - C cab project, I have an edelbrock twin 4 manifold with carbs this has a breather tube hole in the front, I was thinking of putting perhaps a 6" length of tubing coming from there and topping it off with a breather type cap, is it possible to incorporate the pcv valve in the cap ( this would keep everything neat) A friend has told me that I need to drill and tap a location for the pcv near the end of the manifold (near dizzy) so it would work better. My tappet covers have no provision for these items.
