This will make you laugh, when I played the 2nd video, I walked out for 10 secs and when I came back I thought it was a 2nd Ford video and saw the Chevy sitting in the background and thought, geez they could have hidden that or they are so confident in their new engine they brought in the opposition to show off the better Ford engine ![]() Last edited by Dr Smith; 10-02-2019 at 02:15 PM. |

Thanks for the YT advice Franco Cozzo.
![]() Just comparing the GM plan with what Ford is doing: GM has reworked its old iron block vortec line to make the new 6.6, basically has the same 4.06" bore as the 6.2 but a longer 3.85" stroke along with Gen V DI and VCT.... Funny part is that GM is sticking with the 6L90 and not upgrading to a HD 10-speed auto. That would be equivalent to Ford just increasing the bore and stroke on the 6.2 Boss and calling it job done with the 6R140 6-speed auto - Ford would get panned for that but GM gets a pass because well, it the GM small block underdog taking in big bad Ford. Thank goodness Ford went with a two engne strategy, the 6.2 continues in F250 with a base 6-speed auto and optional 10-speed auto while the 7.3 V8 is available across the whole F series range. The new GM 6.6 V8 is rated at 401 HP @5200 and 464 lb ft @4,000 - HD truck power ratings are de-rated roughly 30 HP and 30 lb ft less than light duty F150 /Silvy 1500 power specs. |

IMO It looks like a repeat of what both companies did in the 60's and 70's, with GM operating 2 V8 designs whilst Ford ran 4. Now GM has 1 to Ford running 3.

That’s a good point, because GM fanboys have consistently pointed out how Ford is abandoning V8s to focus on downsizing with EcoBoost. But what we see Ford doing, is giving us all the choices in wngine technologies. Plug in hybrid F-150 coming next year. Full electrification on the way also. I’m sure that tech will come to Super Duty and Medium Duty. I think the 7.3 will be used in hybrid applications also. I have no doubt this engine has been designed for a variety of future applications, as Ford has kind of hinted at that. Just think, they can sell this engine for about $10k less than the diesel with all the emissions hardware. There’s so much Ford can do to reinvest part of that $10k savings and bring the performance up to matching or surpassing the diesel. Eg hybrid, turbos, supercharging. But I’m thinking more hybrid. Especially for medium duty and motor homes.

Getting way ahead of ourselves here, the only thing that's changed is the 6.8 V10
is finally going away and the 7.3 V8 being introduced as a better replacement. |

GM are also not running one V8 now, the heavy duty engine is not LS based, and they will soon have a DOHC engine for the mid engined Corvette. So it will be 3 each. |

They “usually” save DI for turbo’d engines
Correct me if I’m wrong...My understanding was the new 5.0 and LS engines in the smaller car categories had gone DI for emissions. But doesn’t the F250 with this new 7.3 come under a different category for emissions standards?? IE not as strict

The last V6 Commodores are DI.
Thats what the SIDI badge on the boot is for. It does improve fuel burn as the injector is basically right next to the spark plug so the BANG starts straight a bit before or straight after TDC. I have heard that some of the later Commodores have major carbon build up problems in the combustion chambers though???? |

Problem with DI is the carbon on the back of the valves and intake isn't washed off like on a port injected engine.
I know Toyota run both, and I think Ford does too.

Already being shoehorned into a Foxbody. Fit's pretty easily. Plenty of room for the exhaust manifolds. Would need a small cowl hood to clear the front mount throttlebody though. Hopefully Ford sell this as a crate motor with control pack.

Look at how long the runners are on that intake manifold - reminds me of Holden 304 banana manifold.

I reckon if they sold the F250 here with these new engines, they'd have a decent market.
Not US sized market, but I do see a lot of Rams towing huge caravans, and they really have no competition. The only F250 I see is a local's, she uses it to pull her horse float. Does a better job and uses less fuel than the Landcruiser it replaced. Pity we'll never see these vehicles down under. |

320kw at 5,500 rpm and 645nm at 4000 rpm. She's strong.
Will be interesting to see if the aftermarket supports it. Some basic mods to bring the powerband up like intake manifold, cam, exhaust etc could turn it into a good street performance engine. But it's begging for boost. It's been built using turbo spec parts like heavy duty rods, forged pistons, inconel exhaust valves etc, so it would thrive on it. |

Rumour has it that a s/c version will be in the f150 raptor

Aftermarket pistons and rods are on the way, and procharger are working on a supercharger kit. No doubt now this is going to be available as a crate motor if aftermarket companies are already being commisioned by ford to make parts for it. 4.5 inches narrower than a Coyote. |
