How to tell if its a 2005.5 instead of a 2005???

I'm looking at at 2005 f250 with a Manufacture date of 4/12. How do I tell if it it has 2005.5 engine vs the 2003-2005 engine?

Thanks!

how can it be 4/12? like december 4th 2004? I'm 90% sure it has to be bult in jan or later to be a 2005.5 sometimes the car manufactureres get funny and it could be after the 11th month. so its its a 9/04 its a early 05 but if its 01/05 its late 05

Youve got your years mixed up. Any of the 2005 models are fine.

I have a late 2005 and my programer is a 2006 model, I guess the serial number on my 2005 is registered as a 2006
