Ok, so this could be a stupid question and I apologize if it is.

This is the vacuum port for a 283, right? I am adding a vacuum brake booster and I am 95% sure but want to verify before I start taking things off.

Yes Sir, pull the plug, looks like it's 1/4 inch or 3/8 inch pipe thread. Mine has a brass tee threaded in there, one leg is for the PCV, the other for my HydroVac and 2 speed rear end.

The later engines I have worked on (70s+ 350s) had a 1/4" NPT fitting. This looks bigger to me, but it could just be the head.

I will pull it tomorrow. Thanks.

If anyone ends up coming along later and needs to know, it was a 3/8" NPT port.
