PCV on multiple carb intake
 

I’m going to be putting an Edelbrock 4x2 on my 8ba and was wondering if it’s worth goofing around trying to add a pcv system to the engine. This intake has small transfer ports between the carbs. I’m considering installing a system hidden under the intake manifold. I’m thinking if the pcv vacuum port is only under one carb it’s going to affect the mixture of only two cylinders. I suppose a fitting would need to be installed under each carb and manifold it all together? Or am I best to just let sleeping dogs lie and leave it alone and run a draft tube?

I wouldn't mess with a PCV on a multi carb setup, but that is just me.

That’s good enough for me, I’ll forget about the idea. Thanks for your input Jseery.

Multi carb setups are hard enough to tune without added complications.

I am a strong believer on PCV on all engines, however, a PCV on an old flat-head that is in good shape with little to none blow bye might be over kill. I can honestly say that I have never had a blow bye issue with my '36 in the 67 years I have owned it.
I for damn sure would not install a PCV on the bottom side of the intake manifold, having to remove the intake to service the valve would be a huge waste of time.

Suspect you would be better off getting the 4 carbs operating correctly (if you ever do) before considering installation of a PCV system.
