6 or 8#?

 

Ok. I'll bite. WTF are you talking about? No hablo engles?

 

Metro?

 

The 'Metco' system is a pulley that bolts to the crank pulley this then receives an outer ring (on which the belt travels) - The diameter of the outer ring determines how much boost the supercharger will produce. The larger the outer ring, the faster the supercharger gets spun, creating more boost per revolution of the Crank.

 

It's usually used on Ford Lightnings if I recall correctly. I remember talking to a guy with a Lightning who mentioned that setup and said it was common. Try google, I'm sure some shops online would have it.

The 6# and 8# I'm assuming are related to the size of the pulley?

 

Cool. I have learned my lesson for the day.

Thanks.
