Happy Fourth of July to everybody! I decided to post something in tune with the American pride everyone must be feeling on the other side of the border. Have some very intriguing Muscle Car Facts from the cars that started the breed, enjoy!

1. The 1969 Dodge Charger Daytona was always known for its wickedly massive rear spoiler. But was this absolutely large spoiler for abusively high downforce? No! In fact, the spoiler was so tall because it had to give space for the trunk lid to fully open and close without obstruction. This was a NASCAR regulation at the time.

2. The 1976 Pontiac Firebird was famous for its T-Tops roof arrangement, and the closest way to a topless Firebird. The first iterations of this design were done by a company called Hurst, called the Hurst Hatch though they had a leaking issue. This made Pontiac design and build T-Tops of their own and started putting them in the cars midway through 1978. So, in that year some FireBirds had the Hurst Hatch and some Pontiac's own, and they are recognisable by the Hursts being smaller than Pontiac made Tops.

3. The 1969 Pontiac GTO Judge featured in a commercial where a rock band called "Paul Revere and the Raiders" sang a song about the GTO in a lakebed. This was considered to be one of the first ever Rock Music Videos

4. What does the words "GTO" mean?

They mean "Gran Turismo Omologato" and yes it was named after the famous Ferrari 250 GTO. The words in Italian mean "Homologated for Grand Touring" which was the case of the GTO Ferraris.

5. The 1964 Pontiac GTO was compared with the Ferrari 250 GTO by Car and Driver in the 1964 issue. Pontiac realised that the GTO car was going to be compared with Italian exotics, so they cheated gave the GTO a bit of help and replaced the production 389 engine with a 421 cid "Ringer" GTO. The results were surprising, as the Car and Driver mentioned it had made an honorable battle against the prancing horse.

6. In 1969 AMC released a package for their cars called the "Big Bad AMX Pack". This rather optimistically sounding package was actually 3 color choices for the bumpers. Yes, only the bumpers. The colours were: Big Bad Green (Green), Big Bad Orange (Orange), or Big Bad Blue (Yes, Blue).

7. The name "Judge" for the Ponitac GTO was inspired by a skit from the "Laugh In" TV show. The man in charge watched and liked the show quite a bit.

8. Dodge called their line of muscle cars: "The Scatpack" in 1968. Plymouth called them the "Rapid Transit System"

9. Chryslers 426 HEMI engine was called the "Elephant" due to its gargantuan size.

10. 1973 was the last year that the Dodge Charger used Flip Out Headlights. Sadly.

11. How many 1973 4-Speed 340 Barracudas did Plymouth make? Only 1,718, which makes them today extremely valuable and a collectors item.

12. In 1968, Plymouth had a stripped out Road Runner muscle car that lacked some of the equipment of the normal version to improve performance. Dodge needed a competitor, or at least something to compare, so they introduced the SuperBee. The SuperBee sold well, but was always in the Plymouth's shadow. Today, we see the Charger and Challenger SRT's with less equipment than the normal SRT's, following tradition of their ancestors.

13. There were 2 1966 427 Shelby Cobras that Carol Shelby Tweaked and Modified uniquely to any other 427 Cobra. He installed Twin Paxton Superchargers. One was given to Comedian Bill Cosby, and the other one was kept by Caroll himself.

14. The 1967 Ford Mustang Shelby GT500 used Mercury Cougar Tail-lamps, whilst the 1968 model used tail lamps form the 1966 Ford Thunderbird.

15. There is no production 1983 Chevy Corvette, just concepts. Why? Chevy had to change the car due to tighter emissions regulations, and other sources say it was because of glitches the car had. Every prototype was destroyed but 1, and it is at the National Corvette Museum.

16. The Aluminium 427 V8 engine from the 1969 ZL-1 Chevy Camaro is a racing engine that was developed to be used in the Can Am racing series. This Camaro though has no ZL-1 emblems outside, so it looks like any other Camaro of the time.

17. When Buick finished production of the astounding GNX, Pontiac was there to give the Turbo V6;s a new home. The 1989 20th Anniversary Trans Am. Pontiac underrated the engine at just 250HP, but true GM enthusiasts know the potential of the engine in that Trans Am.

Hope you liked learning about cars that pretty much define America!
