I was wondering if anyone knew about a serpentine belt system that would fit on my 1966 389 tripower engine?  It doesnt have a/c but has power steering.  Im restoring my 66 convertible gto that has been in my family since 67. Please help!  

March pulley has serpentine kits for pontiac 400 and 455. I don't know about the 389. They have a website but I don't know the  web address.  

thanks but march only makes a system for 68 and newer pontiac engines
