I am working on buttoning up my 351w EFI conversion. I'm using a trick flow lower intake manifold and Trick Flow Upper. My question is, on the back side of the lower intake manifold is a large hole. I'm assuming it's for a PCV and grommet. Does anyone know what year/make/model i can get this grommet and pcv valve from a parts store? I'm gonna check for a 95-96 bronco with efi, but i'm not sure if these had the grommet/pcv in the back side of the intake.

I have the grommet/pcv for the valve covers, but not sure what it looks like for the back. I swapped out a carbed 302 for this 74 351w block and am adding aftermarket efi/intakes/ fuel rails, etc. ANyone know? THanks

Get the intake PCV grommet for a 5.0 car like '89 mustang. Truck motors typically had the PCV valve in the valve cover.

My 96 Explorer 5.0 GT40 lower has it as well. I bought a PCV valve from Pep Boys for it. Without looking at it right now, I think there's a rubber grommet that goes in the hole. The PCV valve slides into the grommet and is routed up to the upper intake. I think the Mustang lower intake has some type of steel wool type of material inside the hole to act as some type of baffle.
