Classic Mopar Parts – or simply Mopar (which comes from “Motor Parts”) – refers to original auto parts manufactured for Chrysler vehicles. Chrysler first made use of this term in the 1920s, and, since then, the term has become more and more popular and it has stuck until present times. The term is largely used for all vehicles built by Chrysler, such as Chrysler, Plymouth, Dodge, Desoto, Imperial as well as Jeeps and AMC vehicles that were manufactured after 1987, when Chrysler acquired Jeep-AMC.
While Mopar refers to the department of Chrysler responsible for manufacturing parts, many car enthusiasts use this term as a reference to Muscle Car. The association is particularly made with V8 engines and the big block Hemi V8s.
Let’s get into more details
Hemis – or hemispherical combustion chambers – are designed to generate more power than other engines and are known to have been representative for Chrysler/Mopar even before the muscle cars became popular. They were developed in 1952, equipping the 160 hp Desoto Firedrome. Later, when drag racing and stock car racing (NASCAR) became popular, Chrysler came up with great big-block engines, such as the 426 and 440, which are some of the most appreciated classic Mopar parts. As a result, the engines were designed in various configurations and different tune levels. The 426s and 440s were more capable than other Mopar engines or even hemis, since they ran at over 300 hp, and few of them even exceeded 400 hp, without being altered in any way.
The Mopar 400 engine equipping the Chrysler, Plymouth and Dodge is another classic part. It belongs to the B-series of V8s, along with the 350, 361 and 383. In 1972 the 400 cubic inch engine was launched in 2 versions: standard – two-barrel carburetor, and high performance, four-barrel carburetor. Both versions had the compression ratio 8.2 to 1; normal oil pressure ranged between 45 and 65 psi.
The 400 V8 engine from 1973 was quite similar to the engine from 1972, but it had slightly better performance; it also had 2 versions. In 1974, the final production year for the 400 v8 engine, 3 versions were released: a two-barrel carburetor and 2 four-barrel carburetor, differentiated by how they tuned. The standard variant with the two-barrel carburetor also delivered 185 hp, same as the 1973 version, but at higher speed – 4,000 rpm. The four-barrel carburetor variants delivered 205 hp at 4,400 rpm respectively 250 hp at 4,800 rpm.
Classic Mopar parts deliver better performance compared to aftermarket parts, which is understandable, since the manufacturer is the only one that is fully aware of all the ins and outs of its vehicles. The manufacturer is the most adequate provider of top quality replacement parts.
But how much should you expect to pay for Classic Mopar parts?
Well, a Dodge Mopar 440 engine costs about $1,600, for example; a 1977 Mopar 440 cid engine is priced at around $3,000, a Mopar Dodge Plymouth 400 6.6 costs $800 and a 426 Mopar Dodge master engine can reach the $1,200 mark. These are rough averages, so you can find a variety of offers online. Just make sure you purchase the real deal.
Take good care of your iconic vehicle by acquiring classic Mopar parts when any of the standard parts need replacement.
