These cars don't exist!! And here's why!!!

I've touched on this issue before, but it drives me up the wall every time some yahoo starts talking about a car that he or a friend or relative once owned, yet they can't produce a window sticker, build sheet, fender tag, or any other documentation. I'd like to dispel the legend of these "Area 51" cars once and for all. # 1. There was never a Tri-Power 1967 GTO. Enthusiasts were furious when this option was dropped at the end of 1966. The parts could be ordered through dealership parts departments and they would bolt on to the 400 engines. Some dealers like Royal Pontiac would even install them for extra cost, but there was never a factory-built version. Period.  # 2. There was never a GTO station wagon. In 1971-72 you could get the "Endura" ( GTO ) front end and scooped hood on any LeMans model, including wagons. Also, the L78 400 and L75 455 V8s were also optional on any LeMans model. The LS5 455HO was NOT available in wagons. If some yahoo claims to have one, it's a LeMans Sport wagon with GTO emblems.  #3. Still more Pontiacs- There were only 295 SD-455 engines built in 1973, and they were all installed in Firebirds. 252 in Trans-Ams, and 43 in Formulas. The confusion comes from the fact that in early 1973 sales literature the engine was listed as being available in the Gran Prix, Grand Am, and GTO as well as the Firebird line. The buff magazines raved about the two prototypes-a red Trans-Am and a Bronze GTO. High Performance Cars magazine even voted the SD455 GTO their "Car of the Year".  However-the engines had trouble passing emissions with the RAIV cam and it was changed to the slightly milder RAIII cam, and the horsepower rating changed from 310 to 290. They also had trouble with the EGR valve function, and the connecting rod supplier, and the option was nearly killed. However, Herb Adams would not quit fighting for it, and it was finally certified in the F-bodies only in May or June, hence the low production. If your cousin Jethro had a tire-frying 455 1973 Grand Am, it was an L75 250 hp 455, not a Super Duty!!  # 4. There are no 1972 440 Six-Pack Chargers and Road Runners. Like the SD455 the following year-the "Six-Pack" was listed in very early 1972 sales literature rated at 330 hp-down substantially from the 385 hp rating of 1971. However they had trouble passing the stiffer 1972 emission standards and the option was scrapped. Rumors persist that "a few" i.e.-less than 10 "slipped through", but I have never seen one, or seen one verified by any Chrysler engineer or a magazine like Musclecar Review, Hot Rod or Hemmings Muscle Machines, nor have I ever seen a fender tag or window sticker for a 1972 model with this option. # 5. The "Cuda AAR" and Challenger T/A were made for one year only-1970-with the 340 Six-Pack option. Again-very early 1971 literature listed the option. And a Chrysler engineer verified to Musclecar Review that the early brochures had 1971 Challenger grilles airbrushed into the 1970 picture. Further muddling the waters-the 1971 R/T stripe package closely resembled the '70 T/A stripes. But there was never officially a 1971 version released. # 6. There was never any Boss 302 or Boss 429 Cougars. Ford built the Boss 302 and 429 Mustangs to get the engines certified for Trans-Am and NASCAR racing respectively. Bud Moore and a couple other race teams ran Cougar race cars with Boss 302s, but their was never a version sold to the public. The reason was the engines were so different from any other Ford engine and had so many one-off parts that it wouldn't have been cost-effective to make a Cougar version. Ditto for the Boss 429. You could get a Cougar with a 428CJ engine, and a couple of 428 Cougar Eliminators were converted to Boss 429s by Kar Kraft for drag racer "Dyno" Don Nicholson, but their was never a factory built version released to the public; Ford lost money on every single "Boss 9" Mustang, so they definitely didn't need a Mercury version. # 7. There are no 1972 Boss 351 Mustangs. The Boss 351 was made one year only-1971. It was rated at 330 hp,had 11.3:1 compression, a solid-lifter cam, and only 1,806 were built. The confusion starts because in 1972, the compression was dropped to 8.8:1, a milder cam was installed and the engine was re-named "351HO" and rated at 285 hp. Also, there was an 8.0:1 351CJ option that was rated at 266 hp, and the 1972 "Mach 1" striping package was very similar to the 1971 Boss stripes. # 8. There are no LS6 1970 Corvettes. The 11.0:1 compression, 450hp LS6 454 was slated to be available in Camaros and Novas as well as Chevelles, but the brass cut back on model proliferation, and it was only installed in the Chevelle line. It wasn't offered in Corvettes because Zora-Arkus Duntov-( Chief Corvette Engineer ) fully expected the even more radical 12.25:1 compression LS7 to make production as the 'Vette's top engine, but it too was killed by the brass at the last minute. Thus, if you see a 1970 Corvette with a 454, it's a 10.25:1, hydraulic-cammed 360 hp LS5. About 1,100 9.0:1 425 hp ( 325 net ) LS6's were installed in 1971 Corvettes. Hope this clears a lot up.
