The value of the Royal treatment was with blue printing the engine. Without the engine, the only prominence is actual paperwork showing the car was modified by them. And with no paperwork and no engine, the car isn't worth much more than a non Royal Firebird. PHS will not show the mods as they were done post delivery. However....if the car was a pre-order through Royal...PHS may have some hand written notations relating as so. Very rare...and only seen with a few cars.
YY was a 67 428 360 HP block....could be a Royal car. YY was also a 73 400, 74 455 and 76 400. What are the head codes?
