Dealer Order Procedures

one of the above questions is about GM using the COPO process other then Chevy. I don't know if Olds called it COPO but they were sneaky like Chevy and put over 400 cu in engines in some cars also. this is from an Olds site
""The 1968 Hurst/Olds was a limited production of 515 cars. It was powered by a special 455 with W-30 components that produced 390 horsepower. It also came with under the bumper forced air induction, better known as Ram-Air. GM was not allowed to put any engine larger than a 400 cid in any A- body car, so Oldsmobile originally marketed the car as being built by Demmer Industries, but later we found out that all Demmer did was add the Hurst Dual Gate shifter and console, the walnut dash inserts, Hurst/Olds emblems and the special black markings. Oldsmobile in fact had built and installed the Monster Engines without the GM bigwigs finding out.""
