I bought this Supercharger off of craigslist for $400!!!! I scored big time!! Ive always wanted one of these! The kid needed $400 to get his truck back from the tranny shop! So now I need advise. The manifold is a race manifold without water jackets... What can I do? Drill and tap for water jackets? It came with an external thermostat housing. And what is the extra pully thing? Theres no ribs on it. Its not the idler pully because Ive already got that one. And the drive is made out of magnezium, is that ok? Let me know what you think and any advise for the reasembly. I am going to do a write up on the rebuild so I can finally add something constructive to the hamb! I have new bearings and seals comming in the mail. I am thinking my only option is to sell this manifold and buy a new weiland. Tell me what I have here if anything special. I want to get this on my Modified as soon as I can. I have to change to a short water pump and buy another 600cfm carb.
