Wow, your username is quite apt.

Hate to break it to you, but Fords Ecoboost engines are actually heavier than comparable engines, for several reasons.

1st, bigger displacements mean bigger holes. If you take a piece of swiss cheese and make the holes bigger, it gets lighter, not heavier. (Gross example but fundamentally correct). Displacement refers to the amount of air pumped through the cylinders, not physical size. Most OHV V8's are physically smaller than OHC V6s.
2nd, you are adding the additional weight of the turbochargers and associated plumbing.

For example, as a system, a typical(aluminum block and heads) V8 will weigh about 100lbs less than a comparable ecoboost V6.

There's a reason Ford's going to Ecoboost, but don't for a minute believe it's because of weight reduction.

Nice try, but how about comparing them to aluminum block engines, not older iron block ones (6.2L). Also, I went out of my way to specifically to mention cam-in-block OHV, not OHC engines.

LS3 6.2L Aluminum block - 418lbs
3.5L Ecoboost - 449lbs missing lots of parts

Information I had was that weight was without turbos, which I still feel is the case. I don't trust as a factual source, but for now I retract my previous 100lb differential and modify that to 75lbs.
So while this package may weight less than Ford's other offerings, it's far from weight competitive with other manufacturers.

Keep in mind, I'm not knocking the ecoboost line. Just that it gets to me when people talk about lighter (which it isn't), or cheaper (which is most certainly is not) engine. You'd be surprised how many people think ford is doing good financially because they put in a cheaper engine (aka ecoboost).

You're cherry picking the data and comparing apples to oranges. Then the typical ignorant non-posting a$$holes downrate me when I posted facts! Nice try my ass. The 6.2L is a brand new engine. What's old about it? Fact, the 3.5L is LIGHTER than the FORD engines that it either replaces or augments. If I used your logic, I could pick a 1938 Fiat 4 cyl and say that's lighter so therefore the Ecoboost motor is a pig. That might work for you but that's not a fair comparison.

FACT : the Ecoboost is lighter than ANY of the engines offered in the F150. Therefore, the F150 WILL be lighter with that engine installed.
