The Mopar 383-440 70 & Later pulley kit from March Performance is designed for serious engine builders and restoration enthusiasts working with classic Mopar big-block power plants. This pulley system is essential for those upgrading or replacing serpentine belt drive components on 383 and 440 cubic-inch engines manufactured from 1970 onward.
Constructed from high-grade aluminum and ductile iron, this pulley kit is engineered to handle the rotational loads and vibrations associated with large-displacement V-8 engines. The precision-machined components ensure concentricity and balanced operation, which reduces harmonic resonance and extends the life of accessories. Proper pulley sizing is crucial for optimal belt tension, alternator output, and cooling system performance.
This kit is particularly beneficial for owners rebuilding 383 or 440 Mopar engines, especially those restoring Dodge, Plymouth, or Chrysler muscle cars. It accommodates both original-equipment and modern aftermarket alternators, water pumps, and power steering pumps, making it an ideal choice for restorations that blend period correctness with reliability upgrades.
