Whose supercharging their 454 mag?
 
Just curious who or there has a supercharger on their 454 magnum specifically. I have a few curiosities.
If so how much boost are you running?
Is the short block stock?
How much HP do you estimate your making?
How many RPM do you cruise at and how high do you take it?

Here’s a complete bolt on kit from WHIPPLE. I’d be willing to bet boost is kept somewhere near 5 lbs and HP is up around 175
