I'm looking for a valve cover breather for my 383, not one that screws in where the oil filler is but one to go in the hole where the ventalation hose goes in from the tb. The hole is about 1" diameter. Any body have any part numbers. Thanks

 

Found mine at a kragen or a autozone its a spectre filter, part #42856 had to drive 30 mins away to find a place that had it in stock.

 

^ What he said.

 

That's a very common part. Summit, Jegs, parts stores, etc. all carry something like that.
