Fair enoughPushrods...OHC.....eh doesn't matter to me.
All that matters to me is the end result
And how do they do that? Oh yea, they cut out cylinders when cruising. Ford does not do that .........yet. A Dodge running on all 8 cylinders does not get as good a fuel economy as the 5.0 it is simple physics. When all 8 cylinders are banging away and you have to feed almost 50 cid more, and the amount of power required to operate the pushrod set up is more than the OHC, well, it is just a losing proposition.I would beg to differ on that emission/fuel economy statement. Dodge gets better fuel mileage in their 5.7 pushrod than Ford gets in its DOHC 5.0...... Ford has to sell fuel mileage based on the Ecoboost.

I agree, I was just pointing out how they were getting better fuel economy with the pushrod motor and larger displacement. I was making the comparison to show that if it ran on all 8 like the 5.0 Coyote does, then it would not be a contest. When/if Ford ever does this cylinder cut-off thing (I hope not) then it will be game over.Uhhhh......I'd venture to say that they shut off the cylinders in an attempt to give you the best of both worlds. Who needs all eight cylinders banging away when the objective is 30MPG regardless of the size of the V8.
Man they must have really improved their economy. I had a 318 Durango that was lucky to get 15-16 hwy and it averaged about 12. That thing sucked and was in the shop 4 times the first year. I hated that f'ing thing and traded it with about 15000 miles on it. Took a killing just to get rid of it.Meh, both of my '05 Rams got 20-21 mpg and they didn't have MDS. Both 4wd, one with 3.55's and the other with 3.92's
