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.

Thank you, much appreciated.

I would NOT buy a Quanta belt if you plan on running the RPM's up on the car. IT WILL FLY OFF. If you have a NAPA store take the old belt in and match it up. I'm running a NAPA Gold with no issues.

John, if you want me to source some belts and ship them to you, I will.


Let me know

my two cents they are a cheap knock off

I wouldn't recommend a Quanta unless you are never starting the engine... straight into the garbage,
