Several years ago I talked to Quanta about the situation. Their reply "Gee, you're the first person to have that problem".
I found some NOS GM belts for the short belt (crank to water pump) and the alternator belt. Been down the 1/4 mile many times with not one issue. The short belt definitely helps keep the stress off the alternator belt.

I tried a few Quanta's, Napa's, and others, Most either squealed like a pig, slipped and screamed at high rpm, rolled over and/or were pitched right off.

My Chevelle's belts have started squealing at low rpm! I've tried changing them up to no avail! Its a right PITA.

Thanks for the input on Quanta belts. I have them on my 72 LT-1 survivor and will definitely be changing them out for current belts. I also have repros on my 71 Boss 351 - Marti belts, I believe. Are they prone to the same problems?

I've had good luck with Quanta.

Are any of your pulleys powder coated?
