Correct PCV valve ?

The stock PCV valve is smaller than the one currently on my valve cover. Is there a guide or size matrix for these ?

Truck was born a 76' 360 and is now a 76' 390 with the Cobra Lemans valve covers......... I want to replace the old PCV ... I can measure it out, but when I search for PCV's there isn't any measurement's given ...

Thanks

I have a 390 with the same valve covers. I wanted my pcv valve to have a 90 degree bend so it wasn't sticking straight up. I went to O'Reilly auto with my grommet and went thru the bins till I found the one I wanted. I know i wasn't much help but hopefully some. If you want I can measure mine and post it

Thanks for the info and the offer, I think I will do the same this weekend and rummage the local Auto stores for a matching PCV . I also have the 90 degree elbow to deal with........

If you have a Pep Boys near you, they have them on the self-serve shelf, so you can just go through them and open the boxes. Usually its a "low" part number, since you're looking for an earlier application you'll find it on the top shelf.
