Mercruiser SC blower with Super Chiller

Mercruiser SC blower with Super Chiller, pulley?s, manifold and belt for a BBC. The pulley?s are 2.66? top and a 7? bottom. It does not have a carb as I got this setup with a boat I just bought but I cannot use it due to the displacement I will be running. I was told it was fresh from the blower shop but has been sitting for a few years but sealed.
Thanks
