440 with 871 blower in a 318 B body

I just bought a 1974 satellite with a 318 and found a 440 with 871 blower for sale (currently in a 1972 challenger). I am very new to cars like this. What sort of stuff will I need to make this motor work? Aside from a beefed up transmission...

Guy says it has a "mild" camshaft and comes with headers. And is asking $6500, is this a fair price for this thing?
