7.3 Godzilla 790hp NA

[EricM]

no- not what he said. The block for the “Godzilla” (maybe that name applies for the one in the vid but relax Ford) is iron, FE the element. Period.

they didnt “do away with them 40 years ago” despite the rumors hahahahaha hahahahaha

You can't just throw around the term FE when discussing Ford V8 engines and expect people to assume you mean "iron" if there is no other context. "FE" is like "LS" to GM guys. A bunch of legendary Ford engines are FE engines.

It was last used around 45 years ago in production vehicles.

They can do an aluminum version of the new 7.3L block if they want to. It's just more cost to cast and test it. Would save around 100 lbs of weight.

sorry i forgot that my opinion does not conform to your service manual.

LOL. Your opinion doesn't even conform to a comic book. Not an insult, just opinion.

"consider aftermarket mods BETTER than factory engineering. "

Your opinion doesn’t conform to common sense, nor does it matter when its in complete conflict of the facts.

Clearly you’re upset that you got called out for promulgating misinformation, as always, so you you bring up some ******** about a factory service manual. Ironic, considering you’re a hack who thinks he knows more than OEM engineers.

"consider aftermarket mods BETTER than factory engineering. "

It all depends- as usual. Sometime aftermarket is better and more robust because the factory cut corners (rarely), made a design error (not that uncommon) or in 99% of that cases- simply made the part only as good as it needed to be for a stock setup and you are exceeding that. An intercooler is a good example. Ford is not going to stick a huge IC in there if they don't need it. It hurts performance if it's over-sized, plus it's heavier, it could an issue with crash testing or servicing, a million reasons. When you up the boost though, installing a larger aftermarket IC actually does make sense.

Often though, aftermarket stuff is junk and is clearly inferior to OEM parts, ignition components come to mind for example. Some stuff is kinda 50/50, it just depends on the brand of aftermarket parts you are talking about- suspension parts for example.

The argument that EB is modded from the factor is silly though. It's an OEM engine that Ford provides a warranty on. Yes, it's about tapped out- but Ford is already moving on and the 3.5L Cyclone based EB engine will be a thing of the past soon.

so outside of a tune, and intercooler( which im not sure counts as "engine") what are the other mods available for the 3.5ho?
bigger turbos?..more advanced timing?...there isnt much you can do to them because its already been done. sure i will agree it comes from ford that way, but by all definition, engineering, sales pitch, and perf charts the 3.5ho is a modified ecoboost. and so this 7.3 is modified in the same way the 3.5ho is modified compared to the xlt ecoboost.

my only point in this is that the gen2 3.5ho motor is already at its 80% potential output (relative %) because it comes with most of the modifications needed to make a motor more than intended. its like saying a factory stroker motor isnt a stroker because it came that way. and that this 7.3 has much room for power gain from its original configuration.

youre nuts- first of all, the limits to how you can mod an engine/drivetrain- almost any engine- are only your wallet & imagination.

what “could” you do to a 3.5 HO? Well you COULD punch it out to a 4.0, yank the whole top end/rotating assembly & swap for fully forged parts (if the crank isn’t already...think it is tho) can do more aggressive cam profiles, larger turbos, larger throttle body, an intake, downpipes, hi-flo cats or pull em, Bigger injectors, bigger fuel pump, higher volume ported oil pump, intercoolers, rads, you COULD add methanol or E85 comparability, you COULD add nitrous & either swap out for bigger/free flowing heads or have em ported etc etc etc

******** Volvo makes a factory four banger that’s turbocharged AND supercharged lol!

Why even bother comparing an extremely modified version of a N/A iron block HD truck engine to

Feels like I’m about to step into shit, but here goes.

I can understand but don’t actually agree with Porters statement of the 3.5 HO being a factory modded motor. It’s designed, built and sold from the factory in there vehicle. Now if we stay with and use the term modded from the factory, this can also include GM’s ever morphing LS, LSX line etc, FCA’s Hemi’s and Fords Eco variations.

But factory modded in regards to engine design and there intended usage is a bland description. Listening to someone that has inside knowledge of the engine and said it was purpose built, then I’d have to go with that. You could also say it’s a factory modded GT motor then. Sure all makers utilize many existing parts and designs at times and build on them. But to me it’s still a factory design.

Modded motor is a term I’d use with maybe a factory crate motor for off road use. Or a 3rd parties build or your own modded or “built” motor.

“Modded” can certainly be used too loosely, but it’s important on how you use it and to what extent.

My wife had that Volvo Turbo/Supercharged/hybrid in her last XC90. The motor itself made great power and moved that 5k+ lbs Suv very well. A little noisy when off electric but potent lol

Everything you said was accurate up until this. The 3.5 isn’t even close to “tapped out” in stock form; these engines can gain well over 75 HP from a tune alone, never mind the turbo and other bolt-on upgrades that are available. You have a very warped perception of what “tapped out” means.

The 3.5 Cyclone is in the past; Ford stopped using that engine in F-150 in 2016. The Gen 2 3.5 is not based on the Cyclone 3.5; that was the Gen 1 EcoBoost. Ford is also not “moving on” from the current EcoBoost in any way, it was all-new in 2017 and will be the premium engine in the 2021 F-150 along with the PowerBoost variant.

It’s concerning that you continue to post inaccurate information after you’ve been corrected countless times; do you have some sort of memory issue?

There is a lot of debate.

What do you think is the safe RWHP ceiling on stock internals? Consensus seems to be 600/600

It's running nearly 20 lbs of boost already. Please. The current 3.5L is destined for the scrap heap. More displacement using gas, or less displacement and electric will be the direction.

You can call this 3.5L EB engine "not a Cyclone" all you want. It's still has roots in that engine design. That's like saying the Coyote engine is no longer a mod motor.

Edit: Dropped by the SHO forum and guess what is at the top of the forum today? Someone is dropping a crank from a Gen 2 HO EB engine into a Gen 1 3.5L EB engine. It will take a few minor Gen 2 parts to make the crank work (balancer and bolt, sprocket), so it's not 100% plug and play, but it's essentially the same crank. They don't even have to change the bearings.

Same goes for the Coyote. Guys are using the 5.0L cranks in the 4.6L engine builds.

Clearly I know more about Ford's engine architectures and their evolution over the last 25 years than you do. I don't care if you are paid to turn wrenches for Ford or not.
