Just as the title says, I've been wondering why Ford ever swapped over from 5.0? I mean the 5.0 isn't really that great to start with but what's even good about a 4.6? They say they switched it over because it's more efficient, but I really don't understand how they can say this engine is efficient when GM introduced the LSx engines where they are about a whole liter larger, almost 100hp more, and they still can get like 30mpg, which is better than I can even imagine in my car. So could someone please educate me on this?

Kinda answered your own question

I know. that blistering 225 hp from the 5.0 pushrod motor was unbelievable

Im fine with the whole ohc setup but I'd prefer some more displacement so we can at least keep up with our competition.

the mod motor is a better motor, and most of the ls series getting 30mpg is horse **** my friends ws6 (auto) gets about 14

Forever and a day, Ford, Chrysler and GM relied on pushrod/overhead valve engine technology. Engines such as the Ford 5.0, 351,Chevy 454, 350and suchwere prime examples of this. During the late 80 's and early 90 's there was a great push for the "Big Three" to developmore modern powerplants. Japanese and Germanautomakers wereexposing the benefits of single and double overhead cam(OHC/DOHC) technology.One of Ford 's first modern efforts with this technology was theTaurus SHO. Itwas a DOHC, six cylinder built by Yamaha. Chevy 's limited edition CorvetteZR1 employed a DOHCV8. If I recallcorrectly, it too wasengineered by a Japanese automaker(Suzuki?). From that point on, Ford and GMbegan todevelop their ownOHC/DOHChigh performance engines (Ford 4.6, Cadillac Northstar for example).Chevy on the other hand, never strayed too far from its pushrod roots. It conitinued to develop the smallblock pushrod V8 and now we have the LS series to contend with.

[/align][/align]Then I kind of fuzzy on whyyou bought a 4.6L Mustang?[/align][/align]Bob Hall (the self-renounced "father" of the Miata) used to have as his email tagline "If you can't drive fast with 90 HP then 900 won't help." While this is a bit of an exaggeration, it is fundamentally true--going fast and driving fast are two different things.[/align][/align]I once "out drove" an M3 Beemer, in my old 74HP early '86 Corolla sedan (the last RWD Corolla made), for 150 miles on I-10 between Tallahassee and Jacksonville... The poor jerk driving the M3 was beside himself by the time we turned south on I-95...[/align][/align][/align]

Yeah but its was way easier to get power out of a 5.0 than a 4.6. Plus they dont **** out at 450rwhp. They both have their advantages, but unfortunately the 4.6L is more in the "economy, interchangeability" region.
