I don't know if that story is true or not, but I once saw a real original green 1987
Grand National, so who knows. The guy who sold me my GP had the GN in the garage, said that his father-in-law or someone had worked for GM and had the car custom made at the factory (he even showed me the title that it was a GN - he was very proud of it). Maybe that bus driver had a similar opprotunity. I wonder how may G-body's that do not exist, actually exist.
In some cases, such cars were special ordered from GM, and have a callout at the bottom of the SPID. I am not sure if the SPID is like the old Protect-a-plate where the original owner's name is there on a special order car as well, but maybe it is. GM would paint your car any color you wanted if you were willing to pay extra for it and wait. It was a rare thing to see, but a few special color cars did get built every year for a while. Remember: Fleet sales vehicles are ordered in company colors, so it was not unheard of for normal cars to be ordered this way either. The ability to order a car ala carte was one of the things that used to separate an American car from the far more generic Japanese ones. As for legality, the engine was already certified for passenger car applications as it was a
B body engine in 9C1 Caprices. The parts to put a 305 in a Monte Carlo make it a bolt in for a Cutlass as the pin outs on the harness are the same for a Cutlass bulkhead connector as they are on a Monte Carlo in the key areas that matter. If it is a TBI engine, that could have been done using a
Caprice computer and a 4.3 Monte wiring harness and gas tank along with a Monte Carlo exhaust and transmission. That is what makes the story so intriguing to me. I basically did my swap as a 100% GM parts bin install on my car, and everything worked except for the oil pressure light. I used all same year 305 parts from 1985 model year cars (wiring harness too) and the correct pulleys, computer, etc. to make it smog legal (at first...) even in California. It is how I learned all of the stock systems for these cars as well as I know them. I came to love GM for how generic everything was with respect to a given engine family and chassis combination.
