there are none. Both good engines just different in how they make power. Both have seen owners go 1/4 million miles with just proper maintenance despite what some biased owners here try and fling.

and of course look at the torque curve. People should not follow leak numbers unless they will run the power plant at those rpms. That's a complaint folks have about the stang - peak power is high in rpms so ya gotta wring it out to get performance. Doesnt mean it's good or bad just how its designed.

wxman made the statement, still patiently waiting for him to produce the statistics he based it off of...

Oh my....lmao, this is some good reading here. I'm a ecoboost owner that's what was in the truck I could afford bought it with 125k on it and so far so good and came from a 06 Mark Lt as I have stated many times, the ecoboots would run circles around my 06. As far as part count per engine the statements of the eco having more....how can it being 2 less cylinders...like already stated on the general list of parts, Ill add number of bearings in the block, crank, and heads, rings on the pistons, piston pins, injectors, and so on.

Now lets look at the other side of things, and heres a question for the hard core 5.0 guys. So many people have posted how cool a ecoboost 5.0 WOULD be, if that ever happened and the same problems arise what new complaints are you going to have about the 3.5TT? One thing IF it did and the 3.5 is still around guess what the reliable engine will be, kind of like the 7.3 and 6.0 discussions, which one is better....one thing the 7.3 was in production for 30yrs where the 6.0 had 3-4yrs. Ill almost bet the farm you go to the Mustang forums and there is NOT 1 complaint about a 3.5 talked about in their cars and see how many 5.0s have had problems.

Now this is a fun little thought, imagine if the internet was around 100 yrs ago. When the Model T got electric start......"Id never have one of those things look at all the problems they added...starter and some wiring..and I hope they don't get rid of the hand crank...so it will still start....a ton of problems to be had"...lol. How about from flat head to OHV....."Look at the list of problems happening on top of that engine...all them moving parts.....someone else can deal with them..but not me". The big one I bet would of been when EFI took over all the forums would of shut down due to the complaints and gossip.

If you made it this far, it all boils down to this, the 3.5 has chain problems...the 5.0 has block problems, they both can have loss of power, leaks, misfires, and ect. Heres a list you'll never see though, I bet a misfire code wont pop up on cylinder 7 or 8 on a ecoboost, and i doubt a turbo related failure will happen on a 5.0. Both engines are great or Ford wouldn't have sold so many of both and both have flaws and failures. For who ever reads this and trying to decide on what engine drive both research both and get what fits your needs, at the end of the day you will either get a good one or a junk one so gamble how you will. Have a nice day...lol.

If someone does this before they buy a truck, they'll go in with eyes wide open.

Then, drive them, and see how they perform with your own right foot.

When I bought my truck, I drove the 2.7, the 3.5 and the 5.0. In the opinion of my backside, the 2.7 and 5.0 had very similar power. The 3.5 felt more powerful than either. The curves back this up. The dreaded "turbo lag" seemed to be under reasonable control, with that showing up in the 2.7 and I couldn't really feel it with the 3.5.

However - don't buy them based on EPA fuel economy numbers, unless you have a very light foot, don't tow, and mostly drive freeway. To get performance, you need power. To get power, you need to burn fuel. The 3.5 can get worse fuel economy than the 5.0 if you push it a lot. If you baby the throttle, then you won't have much power - which doesn't matter if you mostly do stop/go driving or drive a lot on the freeway (it doesn't take much HP to keep these beasts running fast).

I bought the 5.0 mainly because of the sound. Yes, I really like that sound, even with stock pipes. Way down my list is to put some Borlas in there, which will really improve the sound. I don't tow very often (but, I may tow trailers whenever I can't put something in the bed, which is why I got the tow package), so I really didn't need the power of the 3.5 or 2.7. My last vehicle was going through rear tires every 3-4 months (!!!) and at $250 each, that was getting expensive to display modest amounts of power. I don't expect to be trashing the truck's tires that fast, and as I'm in the "well over 40" club, I really don't need to do burnouts with the truck anymore - that's mostly out of my system.

So, in my (relatively worthless) opinion - buy the truck with the motor that makes you smile the most.

If you crave/need the power of the 3.5 for towing or shredding tires, buy that one.
If you love the sound of the 5.0, buy that one.

Either way, you'll have a great time with the truck!

My Dad has a 2011 Lariat with the 5.0 & I just got a 2013 FX4 with the 3.5. In having driven them both in similar situations I feel like the 3.5 has more acceleration/pick up once you're up to speed on the highway. The 5.0 seems to have more pick up off the line. Towing, they really seem pretty equal to me (towing a 7x14 dual axel enclosed trailer). I think either way you'll be happy. Just test drive them both and see what you think.

LOL, the last two days, I've had two loaners, a '17 2.7, and a '16 3.5. All I could say about either, was, DAMMIT!! Both those things ran very well, and very strong. My '12 has a 5.0, I can honestly say DAMMIT about it as well, including the sound from a good aftermarket exhaust system.
I guess, if I "really wanted" to act my age, I'd take an Egoboost. But screw acting my age, I like the sound, but comparable "stock" power of the 5.0. Especially with a few performance items, after the fact.
But really, as already said, get the truck you like with whatever engine is in it, unless you want to hear a nice V8 sound. That's the only difference I could see. LOL

I currently have the 3.5 eco. I would love a 5.0 with twin turbos.

This is a joke, right? These aren't leak numbers and the Ecoboost reaches is peak torque much lower in the curve, then maintains it long into the range.
