Hello. I never knew that Dodge made so many engine pulleys for their cars. Here is my question. I have a 1970 Dodge Challenger 440 6 Pack, no air, but has power steering. It currently has a polished serpentine belt system on it, that I want to return to a stock pulley system. I've looked on flea bay at every pulley advertised as 440, etc. Question. What are the Chysler numbers, dimensions I need for the crank and water pump pulley. I have the P/S pulley and all correct brackets. Any help/advise would be greatly appreciated. Thanks

 

I would just contact Mancini racing , they can sell you a matched set of pulleys for the set up you have .
there were a lot of different pulleys , different offsets & diameters & bolt patterns for deifferent years & option packages , I probably have collected 50 pulleys over the years , I should just chuck them all as none ever seem to line up !
