tensioner and pulley setup

Hello, I got this setup with my novi 2000. Its a 10 rib setup. Im not sure what it will fit, can some one fill me in?

Its the blower pulley, a tensioner assembly and another pulley.

Anyone know what its worth? Anyone need it?

Any info would be appreciated.

Mike

They look to be the exact same as mine Chevy '98 smallblock kit inc. the supercharger pulley.
