What is the date code? It should be something like G028 (G = July) 2, 1968. It is right by the thermostat base on the water crossover.
It doesn't look like they made any other intakes that end in 4234 other than the 9794234. So if it dates June (F) 1968 or later it must be a 9794234. It is a very good flowing intake that has tested to be as good or better than the after market ones according to Jim Hand's book.
