GM 7 Blade Fan Identity Which one is this for?

[XXXGoldL34M20]

I picked up this fan blade the other week and need help identifying what it is for.
The guy i got it from said it came off a 1970 Chevelle BB car originally.
I know that the 70 BB cars had the 772 Fan Blade or 064 Fan Blade and some came with no part number.
This fan has a "94" and an "H" marked buy the holes.
It also has "FRONT" marked and that is pretty obvious what that means.
What does the 94 H signify ?

The heavy duty cooling option for Novas and Chvelles in '70 (especially a/c cars) used a fan like this. Non #'d, and non dated, 7 blades, pyramid pattern to the rivets.
