I am not up on Pontiac history but you can look at the way Chevy and Olds handled the special factory hot rods. The factory wanted to race but was restricted by upper management rules. They needed to find ways to sneak out factory built cars to meet NHRA rules. Chevy made deals with Fred Gibb and Yenko to process the factory built cars that would meet the NHRA ruled 50 car minimum requirement. Olds built 455 cu in cars that they were not supposed to build and sent them to Hurst to process them. I would guess that Pontiac would have done something with Royal but if they built the 50 cars to race in NHRA then it would be documented. I would be surprised if Pontiac did not build some special cars for in house testing but it is hard to say if any cars escaped the factory. I remember reading an article about a prototype 69 Trans Am with a special de stroked engine and the car was allowed to be road tested by a magazine but don't know what happened to it after that.

DaJudge-- the intake is some type of drag racing fuel injection system made by ALGON with some home made parts to adapt the air filters
