I was contacted buy a guy that said he had a 3 duce setup for a y block, and other configurations.  I seen some of these but do not know anything about them.  Where they something that was created for the y block motor?  What would someone have to do to use a 3 duce setup.  Has anybody used this setup?  I would like to find out about this.  I am not planning to do this but would be great to be able to know some info for my talk with people about these.  Is there any site that deal with this?  Can any one help?
