Well, automakers did convince the EPA larger displacements would equal lower emissions recently. The Boss series engine is well-known to top 7.0 if need to be. Probably for MD trucks but just dreaming of a 7.0 Mustang, Raptor GT, Falcon or all the above....

The union guy said it was going to go in the F150.  HIGHLY UNLIKELY !

 

This likely going to be an "all new" engine.  I am betting it will be a SOHC and NOT direct injected.  Past engines used deep skirt blocks.  More recent engine have not.  Probably just gray iron block with aluminum heads.

 

What will be interesting is if there will be a larger version for the F650/750.

Maybe he meant the Super Duty? That would make more sense. 

 

Also wouldn't a 7L engine be better for CNG applications also?

Yeah, if it's just there to replace the V10, that doesn't seem likely, but they might be considering adding it to other models and lines just for the volume.

I'm thinking miss-quotes or typo.  I can certainly see a 7.0L Boss derivative replacing the V-10 for medium trucks, but certainly not the F-150.  And global?

Given the rising CAFE limits on F150, it's highly unlikely that a large capacity engine will be added,

I can see it going into Super Duty trucks and heavy duty vans, maybe medium duty trucks too.

 

What Ford really needs to do is make the 5.0 more fuel efficient, perhaps cylinder de-activation?

and if that is the case then perhaps a larger Atmo V8 using the same technology has a place

in Ford's larger trucks and SUVs.

 

I'm surprised that Ford did not announce either a V6  or V8 diesel for the Wndsor plants,

that would make a whole lot more sense than a large gas V8.

Curious as to why you think this will be a new engine and not based on the 6.2L 'Boss'.  Not doubting, just wondering.  And, wasn't there to be a smaller 'Boss' on the way?

Yes, that was supposed to be a smaller 'Boss', something like a 5.8L.

And wha happens was the 6.2's power and was upgraded instead.

 

the 7.0 is probably different enough to warrant its own engine line,

perhaps bore, stroke and deck height have  been optimized  for MD use.

As long as a few 7.0L's fall off the production line and end up under the hood of a Mustang or two...... :idea:

A lot of time and several major new engines have been released and lessons learned since the original "Boss" went into production.  Look at the new 3.5L EcoBoost in the F150.  It is pretty much all new.

 

If there is going to be a BIG variant of this engine (>8.0L) then I think it will need bigger bores and bigger pistons.

I would think that Ford would either upgrade the 6.2 into a 7.0 liter with a 104.75mm bore and 101.6mm stroke and stay at the 5.4/5.8 deck height of 256mm.  This would give them .4035" between the bores which is plenty with grey iron. A good Bore to Stroke ratio and probably about a 1.70 Rod to stroke ratio.

 

If they are thinking of a totally new design, say a CGI designed V8, similar to the 2.7 Ecoboost, with CGI block  and innovative lower aluminum pan and aluminum heads, that would also be great!

 

On a F450 F550, it would be great to be able to run on  4 cylinders at idle because many commercial applications have very large idle times with low loads.

 

It looks like direct injection on gasoline engines does have significant drawbacks in unregulated emissions which will eventually be regulated.  Ford going to a dual fuel system, like Toyota, Mercedes probably will go for exhaust particulate traps.

 

Im really glad to see the mid range truck assembly come back to the US from Mexico!

 

I go back to the early 1970's at ford.  Remember the 351M?

I thought that the 6.2 Boss' deck height was 9.41", a little low for a 4" stroke and long enough rods

for a heavy truck application. Perhaps a bigger bore and dedicated Siamese block, 4.125" x 3.75"

stroke would give a nice compact 7.0 with similar deck height.

To jpd80,

 

 

Please check your math because a 4.125" bore with a 3.75" stroke gives you 400.92 cubic inches.

 

My thought is that Ford would try to mimimize investment by making use of all of what they already have, ie a 5.4/5.8 V8 and 6.8 V10  block tooling and line equipment  that manufactures blocks that have a 256mm deck height. (10.078")

 

You would not want a 7.0 liter V8 with a 9.41" deck height for a heavy duty application like the F450/750. Rod to stroke ratio would be around 1.54.
