I wanna supercharge my 7.5
 

after a few years of no internet cable or ac ive returned to the modern world and this amazing forum totally my bronco 2 in the process...a couple times. Ive since moved up to a 97 f250 hd ext cab 4x4 with a 460. and i plan on makin a storm chaser out of it and decided on givin it a supercharger after i get it ready to tackle any terrain I may encounter runnin to/from tornadoes that way i can get the hell out if s*** hits the fan. anyone know who makes a good super for my motor? id prefer a roots type.

A GMC 8V71 would be a good choice. There is a guy in the chicago area that built some good units and packages name of Gary Dwyer, don't know if he's still around though.

I havent seen any roots style of the efi 460. Think you will have to go centrifugal supercharger
