We are looking at a ford f150 4x4 2005 year model . The motor is knocking have been told this is second motor for this truck has had put in it. Will a 5.4 motor out of a 1997 350 series ford van work in the 2005 model ? If not what years will ? Or what can i expect cost to be to repair the motor in it how ?

 

I think that is a 2 valve motor. You will need a motor from a 2004-20xx which is 3valve. As for cost I'm not sure.
