Does anyone know the NOACK for for current or older GC? Tried searching it but could not find any info.

Changed the oil tonight along with a Fram Ultra oil filter(thought I would never use a Fram filter but read good reviews on the Ultra).

Castrol doesn't publish this data. Based on the mfg specs that it meets, NOACK has to be no more than 10%.
