Eaton M90s are readily available (90 ci or 1.5L) from yards. They were OEM on Thunderbird SCs from 89-95 and are OEM on a few GM cars as well, the Grand Prix GTP and a Buick Ultra (Supercharged was an option) and the Buick Rivera (last model).

Compressor maps for these are easy to get and you can get different length "snouts" or drives from Magnueson who rebuilds these things. Check Ebay, typically are a few blowers for around $200-500 or so but I used to get them from yards for less. I worked at rigging up a mount and drive for a 5.0L Cougar I had and it is doable. Key is getting the right length drive shaft so you can mount it where you need it.
