http://www.stovebolt.com/gallery/petroff_tom_1964.html or my Gallery to see my 64 C80 Tandem. I bought it 1967 and still use it around the property fpr maintance.
The 409 was replaced with a 427 in 1988.
OTher than that it's bone stock.
The part number previuosly listed is still good.
Around here at least.
