(Sold)
I'm going back factory correct on my 1969 442 so my Offenhauser 360 dual plane aluminum intake manifold #5768 is up for sale. These cost nearly $500 new so I figure $225 is a good place to start. Date is 10-10-80.

I had painted it Olds bronze nearly 20 years ago and it has held up nicely. You can repaint it or glass bead blast for the bare aluminum look. PM me If you want more photos or have any questions.
