Anybody replaced a 5.4 with a 5.3?

Apparently 5.3 Chevy engines are cheap and plentiful in the junkyards, the reason being they are so reliable and nobody needs replacements. Ford on the other hand seems to have forgotten, if they ever knew how, to build an engine. The 5.4 is a disaster with it spitting out spark plugs and breaking manifolds and bolts etc. etc. I have a nephew in law who has had all kinds of these problems with his. I think if I had been foolish enough to buy one of these and it gave me problems I'd look into putting in a GM engine and transmission. Anybody done this before?
