All 5.4 engines the same deep down??
Hi Guys I bought a 2009 F150 with a bad 5.4. I am taking it out now to evaluate. I have seen lots of 2000-2010 F150's for sale for parts on FB marketplace. I haven't been able to see what engines could be swapped into the 09. I know there are differences in the mounting of alt etc, and the intake, but deep down are they all the same?? Or which years would work? Thanks, Greg. Just found a 07 with a rusted frame.

I don't think you really want that 07 in your trk ?? (older style problem engines !!) You will need a late 2008 engine build ... The magic month being Oct......Fast /Easiest way way to tell is to look @ the numbers on the coil pak tops........New style engines will start with 8L somethink (not 3L )....Look @ a few coil paks in case someone has used a 3L as a replacement...I have only replaced the 4.6 engines & the only difference was the oil filter housing which you can replace with your original housing... Hope this helps & good luck !!

Main and rod bearings look great. But... one of the rocker bridges on #3 is damaged, roller is gone and rocker was laying on top of head. Found parts of it in oil pan and in pickup screen. Then, on drivers side all 4 pistons have touched the intake valves!! Can see the witness marks on the pistons. Also one of the chain guides was broken. I hope the valves aren't bent but I'll bet they are... Well at least the bottom end is good and the cylinder wear is almost none- no ridge I can feel at all. Looks like I will prolly repair this engine. Thanks for all the help guys!!

I bought a set of rebuild 2005 heads and put them on my 2004 F-150? Runs funny.
Is there a difference in the 5.4l camshafts between 2004 and 2005?
