Dear 'Flyer:
Great project! I'll be interested to follow along as you progress.
If you have a few minutes, you might want to look at the web site "uncommonengineering.com" to see some of their interesting projects. They apparently have a (new) vintage "Miller Finned Centrifugal Supercharger" that might be of interest to you. I have no idea what the cost might be (probably not for the faint of heart?) but it sure would be right in keeping with the era and type of car.
