What i was thinking was to use one off of a supercharged GM 3.8 V6, say from a Pontiac grand Prix GTP. It looks to about the right size to mount easily, and should be easy to get one out of a junked car. Or, if yoe get REALLY lucky, you might just find an original S.C.o.T. blower from the '40s/'50s, though the Chevy versions are extremely rare, and not being reproduced like the Flathead ones are.
