Swaping a 94 5.7 into a 98 Chevy Silverado

I have a few questions and after searching the internet this looks like one of the best places to find information. I am not a mechanic by any means, but I can wrench pretty well with a little quidance. I have a 98 Chevy Silverado z71 with a 5.7 vortec that needs replaced. I have found one in a 94 Chevy Suburban. Is there anything that I need to know about this swap. Can it be done without too much difficulty? Is there anything I need to know before doing it? Thanks in advance for any and all help.
