1957 Ford Fairlane Vacuum ports

[oldave57]

I can tell you that the setup in the photos on my earlier post did not result in rough idle or any other noticeable change in the way the engine ran.  You do need to get a PCV valve that is matched in size to your engine (as I recall, I ordered one from Rockauto for a 1966 Fairlane 289 and it worked very well.)

If you can find a way to add a port to a 2 BBL spacer, that would work equally well and would be less work because you really should remove the intake to do the port drilling to make sure you get all the drilling "junk" out of there.  The port system on my 4 BBL 312 works very well with no vacuum leaks either.

Good Luck,
Dave
