Low 60's (61-63) on the main jet for most 2300 series Holley 350 CFM carbs, according to their specs.

#65 PV was stock for all of the 2300's I'm aware of and will be fine for most cases, but this can be changed to match your app depending on the vacuum your engine has.

Thanks, I will experiment around those figures
