And I'm pretty sure that's the only mustang to come from the factory with a 5.4L overhead cam 'modular' motor, other than the new fatty Shelby  .
And the 5.4 has the exact same size bores as the 4.6, just a longer stroke. 3.55 vs 4.1x or somewhere around there. The 5.4 also has a taller deck height for that extra stroke.
I can get much more specific if anyone would like  |
What's the deal with the SVT Lightning motor, I heard that IS a cobra motor...or at least the block or something...
