2000 v6 to 2005 5.3ls swap
Hello all! Looking for advice on what direction im heading in. I have a 2000 Silverado w/ a 4.3 and a 2005 Silverado donor with the 5.3. If I understand correctly, computer on v6 can be flashed and reused on the 5.3. I will need a harness from like year v8. Motor mounts, radiator,heater, ac hoses? Fuel lines?Is there other things that need modifying? 4l60 trans. Dbc. This is a bit of a nightmare. Im new at everything and trying to learn. Ill apologize in advance.
