67 Z28 intake with '65 casting date

[runningbear55]

Not trying to prove it. Not trying to sell it. But...I am pretty comfortable with the possibility that I just may have something special here. And besides...what other explanation is there? What other GM winters dual plane hi rise intake manifold looks just like it in almost every aspect? Why did this part become reality? For what purpose? The expense of casting it Had to be justified somehow. And the "coincidence" that the 1966 introduction of the very first Z cars...with their unique intake (different from the 69-72) corresponds to the date on these 0- manifolds, is enough for me. It just seems obvious. Maybe I'll never know...it's still badass!!
