Difference between 95 5.9 and 02 5.9

Thanks for all of the replies.I was thinking that I would probably have to swap the intake.Some of the other stuff I wasn't sure about.Thanks for the info about the flex plate and balncer.I think I'm going to buy the engine and swap all of the parts.I would like to be able to just drop one in without exchanging all of the parts but i think it's worth it for the price and it's a nice low mileage engine
