97 Swap !help!
 

Hey guys, I was wondering how dificult it would be to swap out a 5.7 EFI and transmission out of a 97 sierra and replace it with an older chevy 350 with a turbo 400. I know I would need new fuel pump for proper pressure to the carb, but is there an easy mounting kit for the engine and transmission for a relatively easy swap? The engine and trans are messed and I've got a line on 383 strocker from an older 350chevy. Any suggestions would be greatly appreciated!
