what year is my engine considered?
i have a 1997 f-150 4.2l flairside.i'm wanting to add a few performance parts to it,but my 1st main problem is this:the person who owned the truck before i did had an engine out of a newer model put in because the original engine had a really bad knock in it.there is a sticker with a date on the drivers side valve cover that says 27 may 2004 along with canada and some other stuff.my first question is this the engine build date? and my 2nd question is if so then is this engine considered a 2004 or a 2005? my local ford dealer can't answer this simple question!
