Why would a 4.6L engine block be stamped 5.4L?
I bought my F150 new in 1998. It only had 8 miles on it when I drove it home.
All badging, plastic trim on the upper side of engine,, and VIN all say it's a 4.6L.
The block is stamped on both sides 5.4L. Always wondered if it was actually a
5.4L. I've driven other F150's with a 4.6L and they don't have the power that
my truck seems to have. My MPG at it's best was around 18 mpg. Are the
blocks the same for both engine sizes?
If you can get a clear view, There will be more "engine" (block) above the freeze plugs on a 5.4. The deck is substantially taller on the 5.4, 2.5cm. The cam covers are different Passenger side Romeo 4.6 has 11 bolts and the Windsor has 14. Look, for a W (Windsor) only the 5.4 was manufactured there in '99. Regards A Ford EXPERT, can tell much more I"m sure.
5.4, look for "X" gussets above the oil pan rails on the block. A good read is here....http://www.modularfords.com/threads/79320- this-should-answer-alot-of-5-4-2v-questions
