Iam new to this forum. Hi to everybody out there. I hope you can answer a question I have. I have a 2003 Escape with a blown engine which is a 3.0 dual overhead cam with an automatic transmission. Can you please tell me if I can use a engine out of a different model Ford but the same size .If yes do I need to get the computor with it or can I use the one I have? Will the trans fit this engine? Thank You.
