The 1970 Dodge Dart is a classic muscle car that has captured the hearts of many automotive enthusiasts. With its sleek design and powerful engine options, it’s a vehicle that has become a symbol of American muscle. However, to truly unlock the potential of this iconic car, one must consider enhancements that can elevate performance. One such enhancement is the installation of a Comp Cams roller camshaft. In this article, I will share my personal experience with installing a roller camshaft in my 1970 Dart and how it transformed the car’s power and driveability.
Understanding Camshafts
Before diving into the specifics of my experience, it’s essential to understand what a camshaft does. The camshaft is a crucial component in an internal combustion engine. It controls the timing of the opening and closing of the engine’s valves, which directly affects the engine’s performance. There are two main types of camshafts: flat tappet and roller. Roller camshafts are designed to reduce friction, allowing for better efficiency and power output.
