Super six manifold

I have a factory /6 2bbl intake but not positive it's a Super Six. I removed it from a 74 Duster parts car I had. I am 15 min from exit 351 (Neshaminy) of the Pa. Turnpike. Probably 45min. from Ambler.
I will send pictures tomorrow morning if interested.
If it's a slant 6 factory two barrel manifold, it's Super Six.
