5.7L Hemi, 1968 Barracuda.. Opinions.

So I have a 5.7L Hemi I got out of my buddies 08 Ram, the thing is in awesome shape but bone stock.. What kind of work can I look forward to if I were to swap my 318 for this engine? The car is a 1968 Plymouth Barracuda Fastback (Avatar pic) Skies the limit right? Just looking for opinions/experience from people who've done it or atleast have more knowledge than myself. Thanks for any help! :P
