1997 5.0 swap

I am wondering if it is possible to swap my 5.0 for a 5.7, and what kind of problems I will face? I have a 1997 Siverado 4x4, and I have access to a 5.7 out of a roadmaster. Any help would be much appreciated. Thanx Mitch

You may have to change the PROM, i know you can swap a 5.7 for a 5.3 or viceversa, any bigger difference will give you problems
