I am planning on a 3x2 set up using my present Rochester 2GC small base for the center carb.What fittings,size, NPT?,do I need for the large threaded hole in the rear of the throttle body which I have read is for a PCV valve.Do most hot rodders keep the PCV valve?I saw photos of one Tri-Power carbs and manifold for sale and the center carb had a 90 degree elbow coming off the back of the throttle body leading to a hose barb,but the barb was capped.Does a hose lead to the PCV valve mounted off the engine?Obviously this is my first build so any information will be appreciated and will be more than I already know on this subject.
