The xram top is from the first batch of the earliest dated crossrams made inside GM engineering for the racers such as Roger Penske and Smokey Yunick. At first in this era, they were strictly backdoor top secret experimental pieces that only went to GM insiders.

Notice the o-dash part number (experimental)...
and the date Dec. 1967...
