Is there a way to date Edelbrock intakes???

[Bernhard]

Thanks for the reply.
The Oldsmobile racer could only dream of such a selection of performance intake manifolds.
I'm building a 69 442 post bench stick period correct Jr stock.
The intake that I'm looking at is for a second engine that I will be building using the O4B4
Edelbrock.
I will be using a Q-jet carb
I have seen a few different versions of the intake and was wondering if I could date code them.
