Default A.I.R pump on an LT1

Has anyone seen or know of a kit that uses the belt driven a.i.r pump on lt1 for crankcase vacuum? I was thinking about replacing the power steering pump with the vacuum pump and make a bracket. Any thoughts?

The AIR pump on LT1 cars is electric, not belt-driven. Look under the hood.

And I'm confused on what exactly you're trying to do...

I know its electric, but the old belt driven one can be turned into a vacuum pump and connected to the valve cover for crank case vacuum. Was wondering if anyone has done it...

i didnt know crankcase vaccum was an issue on our cars... if its that much of a concern to you get a SD tune and throw some breather filters on the valve covers
