390 blower ?possible?
Supercharger USA - 390 to 428 Ford Blower Manfold Blue Thunder 671 871 1071 1471
If you have one laying around you wanted to install, or the entire kit:
Supercharger USA - 289 302 351C 351W 400M 429 460 429 Boss Ford Blower Supercharger Kits for 671 871 1071 1471 Blowers - Superchargers
Google searched "B&M Superchargers" and that was the 2nd hit. There appear to be more, but nothing on the B&M site about puffers.
Your '64 T-Bird motor had at least 10:1 compression stock, so you'll not be able to run much boost unless you go through it and put some lower compression blower pistons in there.
You can get 400+ horse out of a 390 without a supercharger, so go see the FE threads for some build ideas if all you want is power....
