SCHOOL ME ON THIS NEW HEMI SETUP IN 68-70 CARS

I seen where folks are using 727 trans on the new 5.7 and 6.1 hemis. is this a bolt up? also i would imagine it is small block trans right , so would a 4 speed work, is the cranks drilled for pilot bearing, I see they have the motor mounts and oil pan and wire harness,and headers, and to put one in a A body or B body. seeing how i am old school , and have no experience with the new motors, but may try one, i was just thinking.

small block tranny is a bolt up. MP makes a flexplate, but is uses 7/16 convertor bolts. Yes, pilot bushing needs to come out for the snout to fit in crank end.
