Muscle cars! The only definition I know is Ford Mustang! The Mustangs are one of my favorites since I had this awareness for cars and stuff. The latest Mustangs are definitely awesome, but what is more appealing is their origin, especially the models from the first generation Mustangs way back to the 1971-1973 models.
The ’71-’73 Ford Mustang models have resurfaced as larger and heavier muscle cars during this era. After the culmination with the 1971 to 1973 models, Semon “Bunkie” Knudsen was named Ford’s new product design manager. Prior to that, he originally came from General Motors.
Knudsen’s turn as the new design manager saw the last high-performance big-block Mustang - 1971’s 375 hp (280 kW) 429 Super Cobra Jet. A 460 in the Mustang was planed by Ford as well. Unluckily, the very similar body styling that was designed for the sole idea of installation versions of the big block was only limited to 351 in³ (5.8 L) in 1972 and 1973 because of enormously strict emission control regulations of U.S and high insurance premiums was needless for big block muscle cars.
There were 2 additional high-performance engines that were introduced in 1972 - the 351 "HO" and the 351 Cobra Jet. The two models were outstanding performers, but it was way off compared to the standards of the Boss cars and the original Cobra Jet. In 1972, torque and power ratings were altered from "gross" to "net", which corresponded with manufacturers that made low-compression motors with unlikeness, way beyond restrained induction systems. As a result, it turned out to be difficult as when compared to power and torque ratings. It was way different compared to the 1964 models and Ford was flooded by thousands of mails from enthusiasts of the original car who generally asked to bring back the Mustang the way it has been before.
