Royal info wanted

I don’t know what this sticker means to fact, but it has interesting possibilities.

Since it has a round port top end with aluminum intake IV intake, how do we know?

It could have been a RAII carryover block from 68 with IV components added at the factory; could have been a V block installed in Engineering, and obviously some one would have had to change out the cam? Could be Royal swapped who knows what in the car, either from another car or something they got from engineering?

What ever the nature of this block, it pre dates the Florida testing and gives the car another interesting part of the its history.
