When it comes to classic cars, muscle cars have a special place. This place is earned, in many cases, thanks to the work of the Mopar 340. The Mopar 340 is a heavy duty V8 engine that powers many favorite American muscle cars. It is widely regarded as one of the best things to ever come from Dodge's workbench. The engine puts out nearly 300 horsepower, but many enthusiasts claim that the number is actually much higher. And, with a much smaller size than many larger Hemi engines, it fits a wide variety of chassis. The engine is made with performance in mind, with high compression valves and four big barrel carburetors. Mopar 340 heads stand up to some seriously heavy pressure, as the small engine puts out numbers that impress even big-block fans. Over the course of its history, the engine constantly evolved, with better and better iterations earning new fans year after year.
