And unless you're experiencing this exact noise (which shouldn't affect ZL1s without AFM), I'd stick with a stock length belt. Just my 2 cents after building a bunch of blower cars and fighting belt slip.

For anyone interested, the Gates RPM belt in our stock size is: K080828RPM. The stock belt is GM part number 12668317.

Good info, subscribed.
