    Nice numbers. Paired up with the new 10A trans., lots of stump pulling low end torque. Wonder what axle ratios will be available on SD trucks?

    That is a lot of displacement for very low torque numbers, perhaps Ford has lost its Pushrod Mojo and should just buy the 6.6 from GM?

    I just don't see a significant advantage over the GM 401 6.6 HD V8, and the Ram 392 6.4 HD V8 which both are very close without the added displacement.
    I want a car so violent that the mere thought of full throttle would cause a heart attack. That actually going wide open throttle in would result in nothing less than instant death!

    He just had to put us through all that marketing talk.. Why could he not extract more power from such a big motor, I mean, Chevy got more power out of a small 6.2 liter engine ages ago without Di...

    maybe FORD is looking for a very high durability in high demand applications like commercial trucks / school busses and INDUSTRIAL equipment ETC applications where reliability trumps power output

    Please find the Torque Curve Graph of the 6.6L and compare.

    I don't think the 6.6L will have anything Near 400 ft/lbs at 1500 RPM. Even if it did, it would need the Allison behind it

    There were some pretty lofty and now embarrassing predictions for this motor, Ford fans can tone it down now.

    Looks like it's about 360 ft*lbs so definitely down from the larger Ford 7.3L, not too mention will only have the 6 speed.

    Still a nice improvement from the 6.0L.

    Re: Ford's 7.3L Numbers, Lower than we thought









    You'll notice that the 6.6 torque curves appear to be a bit less below 2000
    but what is not so clear is the different way that both engines make their
    torque and power.

    The GM L8T makes its power through a combination of higher compression and direct injection where the new Ford 7.3 uses port injection, less compression and near Stoic (14.7:1) air fuel ratios for maximised efficiency.

    Consider the engines as big air pumps, the bigger the pump, the less stressed it is and that goes to both heat load as well as wear and tear/Maintenance. As part of the feedback from actual F Series owners, Ford deliberately made the new 7.3 V8 as low tech as possible while GM did the opposite and exploited knowledge gained with the 6.2 DI and higher compression to achieve a level of efficiency that would have been thought impossible in Heavy Duty trucks a few short years ago.

    Both engines now exist and like any great GM-Ford battle, the fun is only just starting. I look forward to comprehensive testing of the GM 6.6 versus the Ford 6.2 and 7.3 V8s so that we get to see the areas where the new trucks shine as well as any areas that are not so hot, manufacturers love to talk about the good but what's the trade-off?

    Truck form is what matters in my opinion since we're comparing it to a bespoke truck engine in a truck application.
