What do you mean FI car motor? Or do you mean TT/DI/4VDOHC "car motor" (actually they are engines not motors) Does that imply the vette has a "truck" engine? I love my Chevies, but Ford beat Chevy to punch almost all the headline grabbing stuff direct injection , variable cam phasing, electric steering, and a 6 speed box. Ford gives you a 4 valve DOHC top end with twin turbos- with a forged rotating assembly and side bolted mains. Chevy has the active fuel management which looks really slick we'll see how it holds up as its been tried before, but I think they'll get it right. Uncle Dave The 8 Speed is development, it wont be ready at the trucks launch. |

They just didn't. They chose to massage what they had incrementally. This is why I said they didnt go far enough. The 5.3 isnt even close to the EB The 6.2 is very nice but I dont think it will make 400lb ft at 1900RPM at 4000ft in 100+ degree heat like the EB will. maybe it will- well all see soon enough. Id have rather seen a 4.3 TT with deactivation- THAT would have been new. I tow in Arizona a lot and the heat combined with altitude annihilate NA vehicles. Watch the EB tow my boat on the parker climb out up the hill in 100+ degree heat. https://www.youtube.com/watch?v=PfCEO6ipltA UD let me know when you on the road nextme so i can avoid that highway..:angry-smiley-038: |

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..:angry-smiley-038: 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. UD |

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. 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. UD |

Uncle Dave 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.:lolhit: |

Especially coming off the excellent 7.3 The new 6.7 is getting mixed reviews.... In the diesel world I much prefer the Isuzus UD |
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. |

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