    You are correct but it also goes by all the cars or trucks in the portfolio. So the Mustang will no longer have the Fiesta/Focus/Fusion to offset it. So that puts the Mustang under a bit tighter constraints even though it is a larger vehicle IIRC.

    As far as the F-150 yes it doesn't go by the size of the block. What I was getting at, was that it if it was still a 7.3 it would hurt the cafe ratings, because it would not be as efficient as the current offerings. Ford themselves said this. they don't have to worry about that in the heavy duty vehicles.

    It would be a bit more then just changing the bore and stroke. they would most likely need to add some sort of cylinder deactivation, as well as basically redesign the whole engine. As it is built now, it will be suited for 250/350/450 and motor homes where it could be subject to constantyl being under heavy payloads, heavy towing much more than the F-150 is capable off. So they would need to reassess the engine to make it fit the application of the F-150.

    the F-150 is the cash cow at Ford. Even though V-8 demand is dropping, I can't see Ford not offering a V-8 in the F-150 because they would lose some of those buyers that have to have a V-8. So it is possible that maybe in the future they completely change up the 7.3 and use its base a new V-8 but the engine would need a lot of reworking to be a viable option in the F-150

    GM has been using cylinder deactivation on all their V8s for a while ... that's why they get a decent fuel mileage rating for their displacement.

    I'm betting the heads on the 7.3 are the best flowing two valve style from Ford ever.

    7.3 has cylinder deactivation.

    Hummm...


    I thought this thread fell off page one. Certain death! Anyway, the Godzilla story is just beginning. This is an exciting motor that on the surface makes no sense. But sense it does!


    Kudos for Ford engineering for making a motor by reasoning, without prejudice - and see how the tried and true mechanics came back to haunt the last V8 ever made by Ford. Great stuff and a great story!!!!!

    Hey, I'm betting the 7.3 will be a engine of great desire once the specs are fully known.

    Don't really care about the hp/tq......very conservative 87 octane tune.

    Waiting for the tuners to run it with a 93 octane tune or E-85.

    I just lit Facebook up about this engine on several groups.

    It’s just a solid old-fashioned engine built to last. Nothing wrong with that. Nice to see tried and true designs make it to the end of the V8 run. We shall see how it really is this fall. I’ll let this thread go where it wants now - It’s your thread now. I’m tired of all the personal bashing you have to take just for liking an old-fashioned engine. And I have other things to attend to. I wrote a paragraph that was below about the name calling, labeling and such that goes on in this thread. I’m a hard nose free speech guy, but some of you... But whatever... Goodnight and thanks for participating in this thread.

    I highly doubt Ford is going to completely drop the V8 in the Mustang as long as the competition is still running V8s. The day Mustang is manufactured without a V8 is the day a lot of guys go buy different cars that still offer a V8.

    It does NOT have cylinder deactivation or at least won't have it initially

    "There is a cam phaser on the single in-block cam. It's a simple fixed-overlap kind like those found on GM Small Block and FCA Hemi V-8s, not the Mechadyne DuoCam setup that provides for separate intake and exhaust timing variability like the one used on the DodgeViper. It can rotate the cam up to 60 degrees. Advancing overall timing improves low-end/light-load torque and fuel economy; retarding it at high speeds improves horsepower. Cylinder deactivation will not be available at launch but could be added "

    I stand corrected.....some other media outlets have stated wrong.
    Not a fan of cylinder deactivation......nothing but a headache.

    Really?.....I didn't know that.
    LOL!

    After GM's and Ford's 1st attempt at this mess? I was fed up with it.
    I remember driving a neighbor's Caddy back in the mid 80's just after I
    got my driving permit.
    He hated that car and always handed me the keys........cracks me up to this very day.

    ......and yes, Ford did play around with this concept way back then.

    The Cadillac 4.1L was too advanced for the computer technology at the time. The controller for the cylinder de/activation just wasn't advanced enough to be able to properly handle the changing road conditions quick enough. GM just didn't do enough testing of the tech before pushing it through to production. Which was not unlike a lot of things GM did (or didn't) do. Probably some GM exec demanded this get green lighted and put into Cadillac within some super short period of time, despite everyone telling him the technology wasn't quite ready. "WELL, MAKE IT READY!"

    Ford isn't out of the woods either, as of the 4 Ford vehicles I've owned, only one didn't leak oil all over the front suspension when trying to change the oil filter (1987 Mercury Lynx). I don't know why Ford can't design a vehicle that has an accessible oil filter. And we can't forget about the never buy 5.4 3V.

    Here you go... 600 HP at somewhere around 100 RPM.

    They probably weigh about the same too.

    Seriously......you need to check the fe of all three in their respected shared markets.
    Pretty even regardless of displacement.
    This goes for emissions too.

    Please don't quote back Ford's advertised fe claims, they're in enough hot water.
