Ford 351W Edelbrock Performer PCV Valve

So I have been doing some reading and I think I have a good handle on this but I wanted to make sure. I am in the process of rebuilding my carburetor and I thought I would make some changes while I was at it. Some years back I rebuilt the engine and added a Edelbrock Performer Intake. At that time I reinstalled the factory PCV valve spacer. Now that I think about I believe this can be eliminated. I would like to remove it if possible to gain more clearance for the future motor box insulation installation. I have attached a photograph of how it was installed before it was removed. Here is the order of installation. Intake manifold, gasket, carb plate adapter, gasket, factory PCV valve spacer, gasket, carburetor.

Going forward I would like to plumb the PCV hose to the rear manifold runner. Attached is a picture with a red circle around the proposed location.

When reinstalling the carburetor, It would be installed in the following order.

Intake manifold, gasket, carb plate adapter, gasket, carburetor.


Below are a few pictures and links to parts I have used. Any ideas or suggestions are greatly appreciated. I also plan to install shorter carb studs.

By removing that spacer, you will create heat related problems with the carb. It's been tried unsuccessfully in the past. You might be able to get by with a spacer half as thick, but maybe not.

Ok, Great. Thanks for the information. I will leave it as is. When reinstalling, do y'all like the order of installation I listed.

Yes I have the port on the rear of the PCV Spacer plumbed to the starboard valve cover through a PCV valve.

Carb Spacer may affect performance

Old thread but someone may still need it for reference.

Thermal issues are a big reason to leave it as is, but in addition to thermal there are also possible performance issue.

Have a look at the thread at
http://www.hotrod.com/articles/ctrp-...retor-spacers/

In a nutshell the spacer affects the total volume and that affects fuel mixture. Even 4 hole vs 2 hole vs 1 hole spacers affect performance.
