The stamp looks ok...rough pad, but the 350hp engine is not a typical candidate for a re-stamp...especially in a Nova. That said, the L-34 Nova is kind of rare...there are lots of L-78 cars around...but you rarely see an L-34 car. In the three years the big block was an RPO in the Nova...there were a lot more L-78 cars produced.
For the hot-rodder who wanted big block power without having to adjust the valves...it was a good choice.

Hope to see some photos of this car real soon. Looks like an early car by the assembly date.
