The idle speed can be about the same is the same motor without the blower installed. Motors with a big cam installed need a bit more idle speed.
Motors with a big cam, want a lot more idle timing to idle correctly,
Especially so if the motor has a blower installed.

700 to 1000 rpm should cover it.
What is the idle issue you are having with your blower motor?

With the 144, your idle should be about the same as normal. I ran a B&M 144 Supercharger on my Mustang and my idle was fine at around 750-800 in neutral/ park and it dropped down to 650-700 in drive. If the idle won't stay there, check for vacuum leaks, timing, and carburator adjustments.
