I read an article someone from Steeda wrote about the 09 4.6 being weaker than previous version due to the top ringland being moved closer to the top of the piston. Because of this it makes tuning many times more important as detonation in that engine will cause severe damage. My '09 was built Nov '08. Will the engine serial or castin g number tell me what year it actually is and where can I find that.
TIA
