Help with alternator

I am building a small block (410 CID) strip only bracket racer. I had originally decided not to run an alternator, but after thinking about it for a while I thought I would investigate what it would take to add one to the engine. I am running an electric waterpump and would have to get both brackets and pulley.

I assume with the electric waterpump, a stock bracket/pulley would not work.

Thanks
