Quanta sells this GM Restoration/factory correct looking belt as Part# 29B-602,but cross reference with other MFRs.that might have a different look.And I recommend whomever you buy from,call and ask them to confirm the overall length with you first before ordering,as they measure out at just over 46 inches with Deepgroove pulleys when on the car,(at least mine do when stretched.)
Anything longer is a Big Block SMOG PUMP (YE) Belt.

And Power Steering as you know is a separate belt run by the crank pulley only,and not powered by the Alt. belt.

Hi Rick, the summer here so far has been nice and hot, not AZ hot , but hot for us.

We have our biggest car show next weekend.

Thank you for your advice, very much appreciated.
