Over the years, American carmakers have produced some of the most impressive vehicles ever made. It is often wrongly believed that the names of newer car models are appearing from nowhere. In fact, most popular domestic cars have been roaming the roads for decades. Popular cars like the Corvette and the Mustang have been around for six decades.

The Chrysler 300 is a classic. Though the most recent 300 are looking incredibly sporty and luxurious, the previous editions were just as stylish. In fact, the 300 is one of the most sensible cars made by Chrysler, it has been the case since the mid-1950s. However, anything can be improved upon, as proven by these modified Chrysler 300s.

10 Muscle

The Chrysler 300 was originally marketed as a classy coupe that high-middle income earners would fancy. When looking at the '55 C-300, it is fair to say that the car was far more stylish and luxurious than other mass-produced coupes of the same caliber. However, for petrol heads living in 2021, the original engine will definitely not be powerful enough.

This classic 300 is the sort of Chrysler gearheads would love to get behind the wheel of. Though the car looks as if it was still in its original condition, the entire chassis was improved in order to accommodate a much more powerful powerplant. The modified third-gen 6.4L Hemi V8 was increased to 6.8L. It is fair to assume that this C-300 produces over 500 hp.

9 Chopped Top

The greatest thing about oldies is their potential. Given the numerous trends and aftermarket parts available on the market, it is possible to turn a decrepit, left for dead classic ride into a true show-stopper. That being said, reaching an insane result will require a lot of time, dedication, and financial resources.

The chopped-top style is a style that is very popular in southwestern states. The best part about this type of modification is everything that comes with it. Though this 300 seems to have been kept in its original condition, the car is fitted with a plethora of aftermarket parts.

Chrysler did make some tremendous changes to its legendary 300 car series. From 1955 to 1957, the 300 inherited a much larger front grille and four front lights. The rest of the car was also given a much more aerodynamic back end. All in all, the 300 was increasingly looking like a car that could become a monster.

This mean 300 is the kind of car that proves that Chrysler has always been the king of muscle. Despite its very tame look, this 300 is an absolute beast. The modified 392 V8 found under the hood produces 390 hp. It is quite hard to stumble across a highly modified classic that develops a respectable amount of power. This gem was sold for $77,000.

7 Viper

The Chrysler 300G is the true definition of a classy sleeper. The car was originally equipped with a 6.8L V8 that produced enough power to zoom down the road. As the car was not meant to be a sports car, Chrysler did not put an emphasis on making it extremely fast.

The '62 300 is the most unlikely car to receive an insane engine swap. Imagine lifting up the hood of this rat style oldie only to find a gen two Viper 8.0L V10. Though the powerplant is nowhere as powerful as the newer versions, it still produces an impressive 450 hp and 490 lb-ft of torque.

6 Classic

Another great feature of classic cars is their modularity. Though the trend seems to be to customize them to some extreme levels by adding racing parts and highly-modified powerplants, a very simply modified classic can oftentimes reach the exact same wow effect.

This beautifully modified '61 300 is the definition of sleek. The car is not insanely transformed. No LS swap, no oversized spoiler, no roll cage. It is a restomodded classic that even purists will appreciate. The Ferrari red is unlike what used to be found on cars of that caliber during that era.

5 Slammed

There are tons of great classic cars out there. Though they all have that classic feel to them, they do have features that make each and every single one of them unique. Though the vast majority of classic cars can receive the widely popular restomod treatment, it is sometimes better to maintain their original appearance while adding some tastefully chosen mods.

Several car fans out there simply despise slammed cars. Though it is fair to admit that cars with negative camber look somewhat goofy, a slammed classic with chromed out parts and sick classic wheels are for sure a show-stopper. This beautiful cruiser mixes old and new styles, and the result is absolutely outstanding.

4 Pro Tourer

There is a plethora of tuners, either amateur or professional, that focus only on the appearance of a given vehicle. The most blatant example over the last twenty years or so has been the lifted princesses. Beautiful lifted trucks that are utterly useless. However, it seems that people are increasingly moving towards more performance-based custom trends.

The pro-touring style is awesome. The idea behind it is simple: find a classic ride and turn it into a race car. The 413ci V8 is now rated at 575 hp. Not too bad for an oldie that was never meant to be a monster from hell. This 300 is by far one of the coolest red 300 out there. The car must be even more fun to drive than a modern 300 SRT-8.

3 Simplicity

When looking at the domestic automotive industry, it is safe to say that the second part of the 1960s was its pinnacle. American sports cars were putting European carmakers to shame. Iconic cars such as the Corvette and the Mustang dominated the affordable sports car scene. However, less popular cars were also growing into themselves.

It is quite unclear what was done to this 300, given the fact that the back information on this bad boy is not available. However, it looks like the sort of classic rides that would be featured in a newer Quentin Tarantino movie. It would not be surprising to see Leonardo DiCaprio portraying a maniac gambler cruising down Las Vegas Boulevard.

2 Pro Street

The second part of the 1970s is well-known as the beginning of the end of the American muscle. Though the cars look quite attractive, they are powered by some of the worst engines ever made in the history of American cars. Fortunately, aftermarket parts are widely available to turn these sluggish powerplants into monsters.

This 1979 Chrysler 300 Pro Street was up for sale in Mesa, AZ for around $17,000. The power output this monster can deliver remains a mystery, however, it was claimed that the car could easily hit the quarter-mile in ten seconds. This is the definition of a beautifully modified car from the Malaise Era.

1 Wheelie Poppin'

To most people, wheelie-popping cars really started with Dominic Toretto and his Charger in the very first Fast and Furious. In fact, wheelie-popping American cars have been around for decades. Huge blowers and back wheels the size of an elephant have been popular in the south long before the day Dom Toretto engaged in 14th gear and mean-mugged Brian O'Conner.

This Chrysler 300 is the next level of pro street 300s. The car has an apparent blower and humongous Hoosier wheels, which is a tell-tale sign that the car can easily pop wheelies. It is unclear how long it takes this demonic 300 to hit the quarter-mile, but it is fair to assume that it should be under ten seconds.
