The old 4.9L was the 300ci straight 6 and the old 5.0 was the 302ci V8.

The old 5.0L was actually a 4.9L. For marketing purposes, they called it a 5.0L.

Well as I showed in my above post, even the new 5.0L is not REALLY a 5.0L. It displaces 4,951cc... meaning that its actually a 4.951L you round it UP to a 5.0L. Damn, marketing wins again.

(For those that want to argue this point, this engine does not displace 5,000+ cc's. Even a 5,001cc engine could be called a 5.0L.)


EDIT-
Ford isnt the only one. GM's 5.7L LS1 is actually a 5.665L, the LS2 6.0L is actually a 5.967L. The ONLY GM engine that actually is right on with its designator is the LS7 7.0L wich is actually 7,011cc)

Yes, let's go around and replace all "5.0" badges on 2011 Mustangs with "4.951" badges.

I've gotten in the same situations as the OP, on another thread someone just said that they've had 5.0's in their trucks for years and they've been good. He obviously was assuming they're the same. There will be bugs with the 5.0 just like the EB. Every engine has it's weak points and flaws.

my understanding is that the current 5.0 is part of the modular engine family sharing certain dimensions with the 4.6 so I would say that the family of engines is proven, non?

I don't believe the new line is considered the "modular" motor family anymore. From my understanding, about the only thing it "shares" with the 4.6l/5.4l is the bore spacing, and connecting rod lengths. (rod length with the 4.6 )

Not that they won't, but they also have not released any indications that they'd be basing any further engines off the coyote design, like they did with the mods.

The motor is still up for debate. And yes I'm over here looking to see if the F150 have had any #8 cylinder failers. Been a few tuned 5.0 Mustang's go boom.
