VA Mopar Pulleys Vintage Air, the leading manufacturer of complete performance air conditioning systems for classics, hot rods and street rods, has announced the release of its all-new pulley duo for Big Block Mopar engines. These billet aluminum OEM-style replacements have the look of the original and are designed for both the 383ci and 440ci engines with a double groove water pump and a four-groove crankshaft. Each pulley is machined from 6061-T6 billet aluminum and finished with a black hard coat for wear resistance. The double groove water pump pulley (part #735011) and the four-groove crankshaft pulley (part #735014) are designed to work with an OEM Mopar water pump and accessories and Vintage Air compressor bracket. The water pump pulley includes shims to correct small water pump hub height differences and aid in pulley alignment. Our steel reproduction Small Block Mopar engine pulleys (318ci, 340ci, 360ci) with single groove water pump and double groove crankshaft are also still available. Vintage Air Big Block Mopar engine pulleys are proudly made in the USA, come with all parts necessary for a complete installation and are backed by a three-year warranty against manufacturer defects.  For more information on the Vintage Air’s Big Block Mopar engine pulleys or other products, visit or call (800) 862-6658.
