Sorry guess I should have been a little more specific. The 94-04 mustang does comes with the 3.8, 4.6, and had a stint with the 5.0 however I was talking about the 05-10 model years of Mustang that came with either the 4.0 SOHC
or the 4.6 3V. The three 4.0 SOHC
's are from the same family of engine but I was curious if anyone knew what the specific differences were.
