Original Big Block PCV Valves?

[AMXguy]

Anyone know what an original PCV looked like? I've seen steel with a 90 degree elbow, black plastic with an elbow, white plastic you name it all sold as NOS. what would be correct for '70?

I was told white plastic elbow but I am not sure if that is right or wrong

 ...........CP is absolutely right......white plastic elbow is 1970 up till end of production on all big blocks and 1790 up on all LAs............kim............

That steel elbow PCV valve was used in the late 60's.

 I think the top is white, but the bottom is black. I'm almost positive the one I have in a box is the original piece. Could be wrong but I've owned this thing since '76.  Pete

You're right, I looked on ebait and they're repoping the 70-71 Mopar PCV's and they're a white plasic elbow with a black steel base.
