Anyone Know How Much A Factory 440 Cast Iron Intake Manifold Weighs?

I know that factory stock 2v intake for a 318 weighs 41 lbs.

There's a large flat rate box that fits an intake manifold? How much packing can you put in there to protect the intake?

Ya, i would be thinking the same thing about packaging one of those things properly.

A little side note here.
I just sold a part over on the "C" bodies site, so i will hafta go to the FEDEX terminal Monday morning, sometime, to send it out.
My as well bring down one of my 440 manifolds, and get it weighed, while I'me there.
Kill two birds with one stone, so to speak.
