A-6 pulley
the RPM and HP draw of an A-6 can be reduced by using a larger than stock pulley-i got a pulley off a ~1981 volvo A-6 that is quite a bit larger diameter than the original on the '82 chevy van A-6 i may use on my Z28;offset of the volvo pulley might be different than GM,so i will adjust if needed so belt runs in line.BTW the volvo used an expansion valve-US made,but not GM.
