"Technology" that ford is first coming out with in todays vehicles is 1990's stuff for imports.
All aluminum motors have been used in lots of imports since 1990. Light, better heat transfer, ridged, and in the case of this thread repairable. Iron motors are a thing of the 80's or in the case of american vehicle companies the thing of the 00's.

Aluminum blocks are present in just about everything light duty right now. My 12-year-old FORD Contour has an aluminum block DOHC V6. Heck, my Mustang has a 412 HP DOHC V8 that is shared with the F150. "Behind the times"...heck, find an import making that kind of specific power.
And on the upper end we have the 6.2L gas V8 that's used in the 2011+ Super Duties. Also has a cast iron block and makes even less power than my Mustang's 5.0L of displacement can. As far as I know this is because they need a robust engine that can sing all day at redline and still last for many years. While I think the 5.0L is an incredibly stout engine for what it is, there has to be a reason they aren't putting them in Super Duties.
And finally...find us a medium or heavy duty diesel engine with an aluminum block. These are some of the most high tech engines out there and some sell for over $30,000. Why would they use iron if aluminum was so much better? Don't get me wrong, I love my aluminum car engines, and if Ford ever made an aluminum engine in a Super Duty I'd probably get one because of their high durability standards. But for right now every gas engine they put in their Super Duty trucks is renown for class leading longevity. And they have iron blocks!

This is generation old VW diesel engine that puts 313 HP. Long before Ford was hoping to have 300 hp in diesels.
Even being it old technology, it has no problem to pass current smog requirements.
See cast iron anywhere?

Ask your government why aren't you driving one?

You are right about TV commercials, but being this technical forum -you should recognize the difference between sale pitch and independent technical program that does real testing.

what I cant understand is why the cast block couldn't be fixed I have been welding cast for 25+ years it is more fixable than aluminum
and as far as allimunm blocks I have 1 word to say VEGA for those that rember this in 1974 I believe government motors introduced this little car what a pos but it make a great conversion tubbed out and high hp engines
I would still like to see his new truck

Deck60, yes cast is "fixable" but not nearly as easy as cast aluminum. A cast aluminum block could be easily fixed while still in the truck. A cast iron block needs pre and post heating, Ni-rod filler, and even after the fix you have a high risk of the surrounding cast being brittle and just breaking again. This is also hoping there are no gasket and seals within 6" of the repair or those will need replacing as well.
Cast aluminum just weld the crap and its done, so long as the weld has penetration and isn't full of contaminants it will be good.
Fordguy: cast aluminum is very weldable and the welds hold up very well. Aluminum has a higher melting point and because it dissipates heat so well takes much much more power to get it to melt.
Crazy001: Isn't this fun?
your stang makes 412 hp? What liter is that motor? I ask because honda has been making well over 100hp per liter since the 80's without power adders. I look at engines differently than other people. I look for efficiency, HP per liter and how "clean" the power is.
From what I see companies are just stealing "technology" from other companies. Since honda came out with vtec it took a few years but now I see almost every car manufacturer has some sort of "mivec, vct, vcts, or other cam/valve timing/lift control.
All I'm sayin is the stuff I see in old imports is what I see american companies calling their "cutting edge technology". Aluminum block being one of them. No big trucks with all aluminum diesel engines? Well thats because americans are building the big trucks yet, if import companies would start building them I guaranty they would use aluminum motors and then the americans would all of a sudden switch to all aluminum as well. They just need someone else to show them the light. lol

why does everyone still think you have to weld cast with nirod this is so old school
wire feed prep you want to weld hot and fast and turn you shied gas up to 50-60lbs when you weld it this way do some practice on some junk stuff this is really weird it doesn't weld like you would think. work it like you would a stick
get a heat pencil 400 degrees first just tack and support broken pieces with wire feed heat to 400 weld with wire feed hot and fast wrap it in insulation and look at the next day
have had superb luck doing it this way even exhaust manifolds in place
I had bought a case skid-steer the exhaust manifold was so broken up was just in pieces i took a piece of 1/2 flat iron pre-drilled holes tacked it together put it in oven then welded it back together wirefeed took it to machine shop to have holes edm'ed out so hard you couldn't drill and it has been running this way for 10 years with no problems

Of course I'd really love to continue the off-topic-ness, but that would be disrespectful to the OP and his original thread topic. Would you like me to split this discussion off to it's own thread?

Sure you can go and "just weld cast" with pretty much any welder and filler. But for structural stuff like the block ears nirod is needed.
