    Check out the prices of a Coyote or Vodoo motor, the 7.3 will not be cheap!

    Half an inch less stroke only lowers the deck height a quarter inch, unless you change rod length or compression distance.

    I said this a few pages back, but I'll say it again.

    You're a joke on this forum.
    You're a joke on yellow bullet even more.
    You don't know the basic about any motorsports.
    You don't even own a Mustang.
    You don't know shit about manufacturing or marketing.
    You don't know shit other than to spew useless, false information.
    You couldn't find me any LS swapped S550s. 1 guy, which I found, on YouTube has done it, and not very successfully.
    Lastly, just shut the fuck up already. You literally sound like a dumb fucking 16 year old that works at the local auto parts store who doesn't know shit about anything. If it was up to me, your fucking IP would have been banned months ago.

    For a first cut, I'm assuming that the rod length to stroke ratio and compression distance would be held constant. Quarter inch at the crank plus maybe three times that much in the rod (maintaining maximum rod angle). I can't see any desire in maintaining rod length and pushing the rod to stroke ratio for a pushrod engine out past 1.8 when one of the things you'd be actively chasing would be a shorter deck height.

    That is a good point. All Ford crate engines seem to be a bit on the pricey side compared to GM crate engines

    Forget the peak numbers. 400lb ft at 1500 RPM.

    I'm sure plenty are going to bitch and moan about how this is such weak sauce from a 7.3. They also forget big rigs have twice the displacement and produce sometimes only 50 - 100 more horsepower (yes yes, it's diesel but still). Remember what Ford said they were trying to accomplish: stoichometric efficiency and durability. 430 HP at 5500 RPM is 411lb ft. So basically this engine is twisting out over 400lb ft for over 4000 RPM!! That is called functionality. Exactly what a work horse needs.

    In truck tune.....but only in truck tune.
    Ditch the ultra conservative 87 octane tune.

    Still a far better design than the mod motor derived coyote.

    With that power and torque, I would love to see a marine version of that engine... Even if it was detuned, it would give the 454 a run for it's money, and should be more efficient than the 8.2. It would need to be modded to run at sustained high RPM, would need marine exhaust, and even then I would probably want to run it as a sea-core type with traditional anti-freeze rather than as a raw water application. If nothing else, for longevity.


    I've been toying with dropping a 6.2 in place of my 5.7, but I'm going to hold off for a bit...

    Mustang 360.......Mustangs and Fast Fords have the full write up.
    The 7.3 was and is designed with all out performance in mind.
    The 7.3 is said to be a bit "Shorter" than the Coyote and as we know, a bunch narrower.

    So the nay sayers can cling to the Ultra low 87 octane tune numbers.

    As for me......bye bye coyote.
