Supercharged small block?

a while back my buddy had a super charged chevelle 350. I always like the look of the big super charger on top of the engine. at the time, I thought about putting one on a 360. Problem is, I couldn't find anyone that makes one. I know you can get a side mount one ( like the MR norms ) but I like the look of the top mount ones. you can get them for big & small block fords & chevs, and big block dodge, but can you get them for small block dodge?

if yes, whats the info on them...who , what, where, how much?
