What do I need to change to drop a small block in where a big block was?

Looking at a 84 ish suburban that had a 454 in it but it all got pulled. Found a 383/turbo 400/tcase for 1200 bucks. What will need to be changed motor mount wise?

use small block manifolds if that is what the 454 had and it will bolt right up i think. the monts on small/ big blocks are in the same spot it is just infront of the motor mounts that is diff.
