Carb/PCV line ???

I have a 1992 196 with the 351W HO. I am currently running an Edlebrock performer intake. My future mods list may cause a clearance issue with the carb and the engine cover. My question is if I remove the 1.5" carb spacer, the Edlebrock performer has a threaded plug on the rear of one of the intake runners. Can I install a barb fitting into this threaded runner and install my PCV line there instead of the carb spacer? I talked with Edlebrock and they said it can be used for this but again I just wanted to see if anyone has tried this with any success. I don't want to create any drivability problems.

Thanks!

I don't agree with the leaning out theory that has been tossed around before. I'll have to discuss wiith and expert to double check. It's was done in older cars for years from the factory.

in contrast, I have witnessed funny (lean)plug readings on a Century MkII with a 340, on plugs fed by the runner with the PVC plubing.

The engine has preignition I think is exacerbated from the lean condition but he's too deaf to hear it and too cheap too fix it..Maybe he'll hear the rod exit the block?

Can you just tap into the intake higher, so more then one jug gets the vapor?

Unlikely, the air screws are ineffective once its off the slots and on the mains, when its making big heat.

I called Edlebrock again and just asked them what the hole in the intake was for, without leading them into using it for a PCV, to see what a different tech would say. He told me that port was a vacum port and could be used on a car for power brakes or other needs such as PCV etc. He asked me what I wanted to do with it and I said "Marine application, PCV line". He stated that would be perfect. I told him about my concern that you guys mentioned above about the lean issue and he said "We have no documented problems or issues with PCV lean conditions, that is the intended use of that port...vacum needs". It looks like that runner shares the rear two cylinders. Again...just wanted to check here first if anyone tried and had problems. I will try it sometime over the next few weeks and let everyone know how the boat runs.

Thanks!

my '73 302 came with no PCV system ,would like to install one one this new 331 i am installing in my '64 Am. Skier.read the threads and i too had doubts about an install directly into the intake runner,so i called Ford Motor Racing @1-586-468-1356. have spoken to Ray several times over the years about some of the strange things that seem to baffle the boat dr. when asked about hooking it up on the runner vs. the plenum he says it does not know or care.PCV from one valve cover to the intake runner,the vent from the other valve cover to the flame arrester,problem solved w/no more oily film inside carb.......... boat dr
