I'm going to bang out my supercharger bracket that will put my torqstorm centri supercharger on a 5.3 I put in a 78 vette. Currently with a GTO bracket the supercharger bolts in but the belt routing hits the upper Aarm and front stock bolt. I need to move the headunit up and towards the valve cover more and then I will have to worry about the waterneck and tensioner. I do have a speedmaster electric waterpump I could use as well which will help with the waterneck and tensioner as I could adapt my alternator to be a tensioner probably.

So I will need to pick up some 3/4" billet T6 and probably some smooth or ribbed tensioner pulley's.... where do I get stuff like that? I can find 6rib on ebay but nothing 8 rib and universal. Torqstorm doesn't offer a kit or bracket for the C3 so I'm SOL. Where is a good place to buy pulleys, and aluminum?
