Engine Swap

Thinking about swapping my 400 small block for a 454.
Probably won't happen till after the snow is gone though.
I have a bunch of questions. The engine will be from a 79 Chevy 2500 RCLB.
I will need new motor mounts for a big block correct?
I have a TH700R4 tranny in the truck now. Will that bolt up to the new engine? Or should I use the tranny in that truck (I don't know what tranny it has in it?) Is the radiator I have now enough to cool that engine properly or should I look for an upgrade?
Also I was thinking about upgrading to a TPI or MPFI later. Is that still a good plan with a 454 or should I stay with the carburetor?
Also will the HEI I have now fit on the 454?

Any other suggestions to look at or any other things to look at?
I'm still trying to make up my mind and look at everything before I decide. Plus I want to start filling up a closet with parts if I decide.
