I will Take gen 3,4,5 bottom end over and ford, forged or not. Chevy has had the active fuel management Out since 2005, it works great. now if they would just hang some snails off the manifolds.

The 8 Speed is development, it wont be ready at the trucks launch.

let me get this straight! your towing a boat at 70+mph,up a hill ,talking and video taping whyle doing all this....

let me know when you on the road nextme so i can avoid that highway..

Uncle Dave

By any chance did you count how many people were on said highway?

Not sure talking and holding a 2 inch square box (that doesn't have an eyepiece) is really all that difficult considering a cell phone is harder to hold on too if you have ever done that in your life or maybe smoked a cigarette or coke while towing on a relatively straight uphill road.

- but thats ok- Ill make sure you aren't anywhere near me or my group next time I do it.

I could have pulled this off with no danger in a stick shift truck- what a wuss guys are these days.

Help me understand then how is saying the new engine that has active fuel management a "new feature" if its been out since 05?

Is it new or not?

Dodges 8 speed is in the new Hemi truck and their 6 cyl truck. apparently good for 500+ lb ft of torque.

The Active Fuel Management works great? Realy??? Do you have a 5.3 with AFM? I not impressed with it. We have a 2009 Suburban that had new pistons and rings put in it at 50,000 miles because of excessive blue smoke out the tailpipe and we're not the only ones. If you spend that kind of money on a vehicle, you shouldn't have to go through all this.

BTW, we also have a 2013 F150 with the 5.0 and love it so far.

Go read on the LT1 or gen V if you want all the tech details.

The AFM has been around, but was instituted rather conservatively in gen IV due to NVH and some other problems. I'd expect it to return much better efficiency in this implementation.

Yes, the ecoboost is a car "engine" (pedantic much?). Time will tell how it handles duty cycles of a truck. I guess Ford's strong history of bulletproof truck motors should give people confidence.

Uncle Dave

The 6.blow series was sure atrocious.
Especially coming off the excellent 7.3

The new 6.7 is getting mixed reviews....

In the diesel world I much prefer the Isuzus

kind of dissapointed in the unveil. Truck looks nice and chevy finally updated the interior to look like it belongs in the 2000s. But in the end the truck looks like a refinement more than anything. They are saying these engines are new, but really theres nothing new to them. I was hoping they would provide an EB option and or a small diesel option in the half ton.

GM has not put performance numbers out yet, but they did leak that their 5.3 will have 350hp, wow good job chevy way to put out an engine that has less power than your competitors. To me it just looks like they made there new truck to compete with whats out there and not surpass anything that is on the market.

I got 15k on mine in one year towing a 10k boat and no issues yet. I have not heard of any EB problems to date from anybody. Swing by the dealers and you cant find them used people are hanging onto them. As for the eco, the 3.5 has been out for a while now in cars and such for a long time, granted throw turbos on its kind of a different engine. Europeans have utilized this concept for years of having a smaller displacement engine for mpg and turbos when power is needed. To be frank I dont care how many cylinders it his, i am concerned with performance, and right now there is not a stock 1/2 package that can tow 11,300lbs, have over 2k payload, and get the mpg that the eco gets.
