Swapping in a hemi 5.7

itd be nice to have the old push button tranny hooked up to the 5.7 (id have to find a tranny with the v8 bellhousing), but a more modern day tranny with cruise control would be nice as well.
i want my car to be a cruiser also, but when its all done (years down the road), i want to take it to the track and see what she gets in the 1/4 mile.
i checked out that street performer website. i have a question regarding the motor mount plates. my car is a /6 now. im getting (with my car) the v8 motor mount adaptors. will those plates mount to the motor mounts and then to the /6s k-frame or will i need to do something else?
