Timming with a vacuum gauge.

When using a vacuum guage to set the timming, do you hook it up to the bottom of the carb or the manifold of a blown (supercharged not broken) engine?

The bottom of the intake would be best.

You cannot set the timing with a vacuum gauge. Get a timing light.
Supercharged motors like a lot of intial idle timing.

You'll need to recurve the distributor to get the timing right.
The out of the box timing curve of a stock or typical performacne distributor will not work well.
