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.

motor mounts will work trans will bolt up you will have to fabricate exaust and all your brackets will have to be for small block
