The 2-groove nos Mopar crankshaft pulley for 1969-72 Plymouth and Dodge vehicles equipped with 383, 400, and 440 engines is an essential upgrade for any performance enthusiast. This precision-engineered pulley, with part number 2946789, is designed to replace the original equipment manufacturer (OEM) pulley and is specifically designed for high-performance applications.
The 2-groove design of this crankshaft pulley is a departure from the traditional 3-groove design, which allows for the use of a larger diameter drive belt. This larger belt can provide more torque and horsepower transfer to your accessories, such as the alternator, power steering pump, and air conditioning compressor. The 2-groove design also reduces the overall pulley diameter, which can help improve engine breathing and reduce parasitic losses.
This pulley is made from high-quality aluminum, which is lighter than the OEM pulley while still providing excellent strength and durability. The aluminum construction also helps to dissipate heat more effectively, which can help reduce the operating temperature of your engine. The pulley is also finished with a black anodized coating, which not only looks great but also provides additional protection against corrosion.
The pulley features a 1.75-inch (44.45 mm) bolt circle, which is compatible with most aftermarket accessory drive systems. The pulley also includes new bolts and washers for easy installation. The pulley also has a diameter of 7.5 inches (190.5 mm), and a width of 3.1 inches (78.74 mm).
In conclusion, this 2-groove nos Mopar crankshaft pulley is a high-quality upgrade for any 1969-72 Plymouth or Dodge with a 383, 400, or 440 engine. It provides improved performance, reduced parasitic losses, and improved heat dissipation, all while reducing weight and looking great. This pulley is a must-have for any serious performance enthusiast.
