you're looking at anywhere from $3000 for used engine, new trans, wiring harness yourself, labor yourself, to $19,000 for brand new 450HP ls3 corvette engine, New transmission, so on, so forth.
The most common swap? That would be the chevy 4.8/5.3 v8. You can get these engines from all chevy suburbans 2000 to today and I think all chevy silverado/Sierra extended cabs. The regular cabs came with the 4.3 v6.
These engines put out about 300 hp which is plenty enough for our jeeps... Unless you want to just go all out.
Novak conversions is a great website to look at for information!
