The only Superchargers I know of that
would have made it to the wrecking yards
are from a 3.0L engine, you would have
to spin it at half speed to keep the boost
down. Look for an SC Thunderbird or some
of the Lincolns perhaps. Do your homework
Superchargers are a lower boost device, not
happy over 5 PSI, and stock pistons can't take
over 5 PSI.
I'm getting custom pistons made, forged, low
compression, about $600 with pins and rings,
if you are looking for more power than 5PSI
will give you (about a 30-35HP jump) you might
think about a turbo instead
Good Luck
