Cost on swapping engines in a 2002 1500 pickup?

I don't believe anyone has a simple "it costs XXXX" answer for thsi because it depends on the engines you want to swap out, the condition of the engine, the garage you're going to, the make of engine and possibly any other costs that may factor in such as changing fittings, attachments, etc. A ballpark figure I suppose assuming it is a simple swwap of identical engines without any problems would be around 150 euros and take around 3 to 4 hours straight work. In practice I wouldn't expect to get my car back for 2 days and pay around 250 euros. My advice, phone around the garages and get quotes before going in person. They may also need to see the vehicle before giving a quote.
