1991 suburban 350 to 454

[ww228king]

OK guys! I am new to the forum so this may have been mentioned before, but here we go... I have a 1991 4x4 1500 suburban with a blowed 350 FI. I have been given a free 1995 2wd 2500 suburban 454 FI engine. Nothing wrong with the 454, he just swapped out to a new crate 502. Here are somethings that I know that i will need: headers, intake to change to carb, bigger radiator, and prolly do some motor mount mods. Ok i need to know what headers will work what will i need to do about the motor mounts and what other problems will i be running into. I will be bolting it up to the existing tranny. Ok guys tell what you know. Thanks!
