Steve Morris does'nt work @ Steve Morris Racing Engines anymore... I know it's odd his name is on business he is no longer affiliated with but... just FYI you won't get ahold of him there. Last I knew he was @ New Era Race Craft, but I think I may have read he bounced around again after that but not sure.
But that being said, there are lot's of people/places that can build a good ProCharger motor/give you good advice. Getting camshaft right is really biggest hurdle, the rest is pretty straight forward. As far as the actual engine goes....It's just a blower motor...
Mounting/packaging the Procharger is much more difficult than building good motor for it.
