Anyone know what the ATI balancer 3 bolt pulley would be from? I ordered a pulley thinking it was 4 bolt like the factory one. Looking for a serpentine pulley for the crank.

I got a response from ATI and they said it’s either the 3.2 Chevy bolt circle or the Ford 3.2 bolt circle. After looking for a pulley I ordered the 4 bolt and do plan on redrilling it.

The Ford 3 bolt is a slightly larger bolt circle but, either usually works.
