Not period-correct. The Victor-style manifolds came out in the Eighties. This particular manifold was probably used in a Marine application, hence the backwards-mounted carburetors. A neat manifold to maybe keep an eye out for would be a late-Sixties style Weiand dual quad/dual plane manifold. I've seen them on original Nickey Super Camaros when the customer requested dual quads and the neat thing about it is that it is actually very very reminiscent of the Chevrolet dual plane factory hi-rise intake. It's a great looking manifold and if it weren't for the Weiand script, it would look like a factory Chevrolet offering. Being of the dual plane design, and with a couple nice vintage Carter Competition Series carbs, it would be a great Street/Strip manifold.
