Not sure what pulley size to go to with my mods anybody running a 3.5 or 3.6 pulley setup? what would be better

Im pretty sure I would get zero knock on a 3.6

My mods:
3" zzp dp
zzp fenderwell
Hptuned
AL104s
Drilled 180
powerlog

 

Being pretty sure, and having a gauge to test for knock are different.

I always say start high, get a modular pulley system and see what your readings are.

 

Will do, thanks
