Looking to modify my cast iron 442 455 intake for the PCV in the intake, has anyone done this before? Anyone know where to buy the nipple for the intake?

 

I believe Octania [Member here on CO] has done that very thing.

 

I had to do this on an iron 455 manifold on a '72 that I converted over to OAI and manual transmission. Chris sent me a nipple and precise instructions on where to drill and what size to drill to. Worked out beautifully.

 

W30 fyi Octania= Chris

 

I got in contact with him, Thanks all.
