So, let's say for example, one is running a B&M blower with 5 PSI of boost. Will swapping to a 6-71 running 5 PSI of boost on the same engine result in more power?

Absolutely! The slower you can turn the blower and make the same boost, the more power it will make. Also remember that boost is a measure of unused manifold pressure below the blower. You can improve head flow/camshaft events and LOWER boost and RAISE horsepower! Have fun...
