built a 408 small block. supercharger options?

that compression would probably work ok on E85,thats the advice i have got on my 340 i dont have a stroker so that makes for less dynamic compresion but from what i have been told i could ad as much as 14psi of boost to this compression on E85 without detonating (wont happen untill i get an R block and alot better pistons but thats a diferent storry)
