If they just added two more pistons to the 3.5L it would be a 4.7L but if the performance scaled up by 1/3 it would produce 626 ft-lbs of torque and 500 HP!

I am sure there are F150 owners putting lots of towing miles on theirs and I haven't heard of this being a problem.

 

Could be done that way, but ...
A 90 deg v-8 makes sense.
A 60-deg v-6 makes sense.
I'd not want a 60-deg V-8. Makes for more balance issues and complexity.

Further, I'd rather have a larger displacement engine based on the 6.2L because it's had stellar reliability over the other two. (not saying they are bad by any means, but the 6.2L is essentially problem free). Bump up the stroke on a 6.2L to perhaps 6.5L or maybe 6.7L , re-tune the ECM to maximize that change, and net me a bit more torque down low, and I'm happy!

Plus, I'm to the point in my life where simple is better. It's not that I dislike turbos (I own a few), but the EB engines have a LOT of plumbing to deal with; plumbing that will go bad eventually. Cooling lines to the turbos, oil lines to the turbos, etc, all have seals that will eventually leak. And those are NOT easy to get to for replacement. More seals means more leak points; maybe not now, but down the road.

About the only "technology" I'd be interested in is if they decided to do the dual-fuel PFI/DI system on the big gasser engine like they have on the smaller engines. That would broaden the torque band a bit and also net a bit more efficiency (due to higher CR; efficiency is directly related to CR).

 

You guys can forget your ecoboost superduties. Not gonna happen, at least anytime soon. If you want turbo power, it's available in the form of a 6.7. Good news for us N/A guys is the 7.0 that will be here within a few years. I'm not against the ecoboost, I particularly love the 2.7. But I don't see those motors holding up 300k and being trouble free when worked hard very often like many super duty's see. Just the added weight of a super duty would have them building boost a lot more often than a 150.

 

I agree about keeping it simple and therefore robust but the 3.5 EB has been in widespread use for about 5 years and has proven itself. It would be great to have that or a larger version as a 3rd engine option on the Super Duty line.

 

Good luck with that option. I'm still waiting for paddle shifters!

 

Arnt we all?? that being said.. paddle shifters on a super duty.. just seems a little wierd

 

Not weird at all when you consider the most manual shifting drivers are in a super duty towing something. I've encountered Granny's driving Fusions with paddle shifters that never even knew they were there, let alone what the heck they were for! Somebody at Ford doesn't realize how we drive our trucks.
