- REVan Evan and Brian Wolfe dig deeper into the all-new 7.3L (446 cube) Godzilla and show the pistons, crankshaft, rods, and you'll see a block cut open to expose the water passages. Brian also covers how big a Godzilla can go in displacement. Coming up next we discuss camshaft, valve train and the oiling system. Here's a link the first two videos in case you missed Part 1 and 2.

I read somewhere that the Ford designer of this engine is a drag racer and knew this motor would make its way into the hotrod scene. Also it will help Ford take away from the LS base and its about time. Lovin it !!!!!!!
It probably won't poach a lot of LS users until Ford makes an aluminum block version. Of course, the stock iron block will be great for boosted drag race applications...
Can we all just take a moment to appreciate that the cam is inside the block like God intended?
Are you not familiar with the SOHC 427 from the 1960's!??
@@jeffmiller3150 well yeah, Pontiac fooled around with one too.
The cam belongs in the block.
😂🤣 yeah. No. It's for sizing. The 5.0 coyote makes 460hp/420lbs of torque on a mustang tune. If this thing wasn't gonna be enormous, an ohc version would easily be 500hp out of the box
@@PureCountryof91 I'm sure GM engineers could wring the same power from a 5.3 if it wasn't a truck engine. Big deal.
PureCountryof91
It’s not just sizing. It was also simplicity, low end power and longevity under load. This was always intended to be a commercial truck engine. But let’s just appreciate that we get more Ford engines to play with
@8:45
"We cut this block with a bandsaw." Thanks for sharing. Great info
Thank you.
thank you henry ford. for all the fun you have brought all of us gear heads.
The 7.3 stuff is 🔥🔥
1800 HP.... unbelievable we're talking these numbers and the crank is a definitely a chunk of badass! This man does a great job at explaining the features...
You've surrounded yourself with a lot of knowledge E 👍
Did damn thing ain't going to make no 1800 horsepower gtfoh
600hp mate. I have an daily driver powered by an unopened Barra making 800hp. That 7.3L is a massive boat anchor.
@@nordic5490 lol do u not realise people make 3500 from those 5.0 fords? Id ne surprised of they dont hit 3000 with this knowing the yanks
billy heaton yea tell me about it specially on those toothpick rods
Nor Dic no way stock bottom end of Barra making 800hp
Since both the 7.3 and 6.2 share the same bore spacing of 4.53" we are looking to put the 7.3 crank in a 6.2 SOHC! According to Brian the main and rod journals are the same size... So it's party time!!
Thanks Again for such awesome Vids...
Do people swap the 6.2 into mustangs? Excuse my ignorance I’m in the uk so I’ve never heard of it.
2011metalmaniac no one does that in the states
Why what’s wrong with it?
I wonder if you will need to clearance the block for the rods?
2011metalmaniac One of the reasons are that it is to big and the 5.0s and others are better anyways because they’re lighter and higher reving
I'm a pretty DieHard LS guy. But I can't deny the fact Ford has really been stepping their game up since the coyote. And this engine has me excited especially that it's a push rod. Way to go Ford.
Yes Ford has some really great engine packages.The Coyote is a monster,mid 9 second performance with low boost.Personally speaking I would advise builders to turn down the power if the car or truck is going to be driven on the street.The big HP numbers work best on the racetrack.
Being a Ford guy, I don't like this engine being called "Godzilla". That names already been taken by a legend.
Yea and Godzilla is Killed by the Japenese in the end also. Not a Good name for American Muscle.
@@imakittycat1302 I was referring to the RB26 who's claimed the name "Godzilla"
Aaron Keller yeah they could’ve called it Hercules or King Kong or whatever.
"Clydesdale" would have worked
@@aaronkeller8269right wouldn't more of an appropriate name been King Kong
I'll keep my old 460 thanks, it's been on the road since 1983 and has 480,000 miles on it and still runs like a champ. Not dissing the the 7.3 or anything, its a great looking engine. Might be a fun swap later on.
I have farmer friend with a 460 powered water well. After ten years (about 65000 hours) it is still running strong.
was the engine ever rebuilt? what kind of oil do you use?
Going to be putting in my order for a 7.3 F350 in early fall. The more technical detail I see around this engine the more excited I get. Thank you for these videos. Very informative and well done. 👍
I really want to hear what one of these sound like through some headers
brapppp
Yeah, with a nice choppy sounding big mutha thumper camshaft and some 2 inch primary headers. Bet it will sound like a monster! Nothing sounds as badass as a big cube motor with a long duration and a tight lsa cam running thru some quality big thick tube headers and a set of 3 inch in/out flowmaster 10's !! Man!! I can almost hear it now rumbling from under the hood of my black metal flake 65 mustang fastback with 15x10
Cragar ss on the rear and 15x4's on the front .
And a smile plastered ok permanent on my face. Lol
It's not mentioned, but the crankshaft laser hardened, superior to induction, developed by Ford and and an industry first. The first engines crank is a prototype, as it's discolored from furnace tempering.
Thank for mentioning that and for checking out our channel.
GM was doing laser hardened cams in the 70's and 80's.
@@andyharman3022 Sorry, but in the 70's and 80's a 6kW laser did not exist to the public, and the military didn't even have them. You are likely confusing this with induction hardening, which largely replaced conventional heat treatment.
@@mikekopmanis2099 Didn't need 6kW to do laser hardening of cams. The laser was pulsed to heat a spot about .030" diameter, then turned off to allow the heated spot to mass quench, thereby making the martensitic transformation for hardness. If you would look at a production cam from that era, you would see the raster pattern of hardened spots. Not likely that I'm confusing it with induction hardening, as I wrote my engineering thesis on contour induction hardening.
Need one of these in my 84 Bronco. Thanks for the great video on this, everyone has been waiting to see in detail the godzilla
Thank you for watching!
I normally dont comment on these things but that was great content you have answered most of my questions about this block solid info all around
Thank you Ryan, I'm all about the detail. Much more to come.
Fork me i love those heads, everything we always wanted, and its stock!!!
Would be so easy to do individual stacks on this like an old school FE, speaking of which the bottom end is designed similarly and i am in LOVE
@@smokenchoken1736 it would sound so good with 8 stacks screaming at wot
Would love to see you optimize the 7.3 for max low end to mid range torque. A real stump puller for RV hill climbs!
That’s great Evan, I never knew that you had a channel. Was a fan of your column, wayyyyy back
Thank you Jim, let me know what kind of stuff you want to see.
Evan you’re doing great man, usually you’re covering the newer and some of the one off stuff. I go to Uncle Tony for the older stuff. I remember you driving The Fridge when that was new, I still have my Lightning.
Always nice to here about your video and knowledge thanks! Happy motoring 🇨🇦
Only thing I’m not crazy about is water pump bolts going thru front cover but I suppose if your a die hard ford guy you’ve about got all the gasket timing down. Can’t wait to see what a cam will do. The intake and exhaust manifolds already look good so I doubt theirs gobs of power to gained but still exciting to see these vids! Keep it up
Very modular like design on the bottom, and that is muy bein!
When you see the cutaway it gives you mad appreciation for the strength of iron. This should be the only V8 option in the F-150 on up.
Great video i cant wait to see what people do with this motor
I don't subscribe to very many channels but I just subscribed to yours. Great content and delivery !!
He's one of my favorites. You'll probably love my channel too...
Thank you Rick, let us know what you'd like to see.
This Motor is gonna be sick!!!
This could be an interesting series, except instead of all the commonly rodded out motors that there are a billion videos on, it would be interesting to see some of the new half ton diesels and everyday ecoboosts etc. all pulled apart. No one breaks down the engineering in some of the most common engines like this. I particularly find it fascinating.
Great video. Fantastic stuff from Ford.
Thanks
This engine is using all the good designs of the past, the full skirt block of the FE and Y block, the cantered valves of the Cleveland and 429/460 and the timing cover a bit like a Windsor, just hope it has the firing order of the old Y block to get that sound. Also with the chain driven oil pump there must be a way to drive a external oil pump to lower the oil pan for engine swaps/racing
Fractured rods are awesome. In caterpillar land we have been using them for ever. Although all the bolts we use are torque to yield. I dunno about this ford rod but it’s something to keep in mind if guys are going through there oem rotating group to balance it or whatever they may need to change the rod bolts. Maybe they will make an arp bolt or something. Please put some pistons and rods in this engine and a 102 on it and a little methanol lol.
Keep’em coming! Love the channel!
Thanks, you got some great videos yourself, cool channel, great Foxbody content.
I've been waiting for this...
Thanks for putting 446 cubic inches. I’m old. Like oil filter placement too. Whew, nerve racking music at start and end!
It’s actually a 445.
Great video and education!!! Thanks for sharing!!!!
I've been waiting over a year for this engine release and foxbody swap kits to become available. I have a 93 2.3L notchback that I will be doing this swap to. Very excited for this 7.3L.
Thanks for watching, we have much more to come.
I've also got a clean built 90 coupe with a 393 F4TE, I intend to pull and swap for for the 7.3 as they become readily available. The 393 will eventually go into a 53 F100
2:23. Shot of block deck and pistons. Pistons look like inverted dome big-block Chevy pistons I used 20 years ago. The close proximity of the intake valve notch to the piston od will make it easy to burn the edge of the valve notch out of the piston if too much spark advance is set. The saw cut is good for cooling the inter-bore region on a heavily loaded truck engine, but may limit max overbore.
Nice background diecast and wall art!
Great video! Would love to have a version of this engine in my Raptor.
Me too bro
This series is very cool, you got a new sub
Thank you, glad you're enjoying our content.
Great 7.3 content. May I suggest you create a playlist just for the Godzilla videos?
I want to put one of these in my 96 F-superduty(450) reg cab flatbed!
Same !
more like a Hirth sled motor, i got a few gallons of XD-100 BRP for these sexy 2 stroke 7.3's!
Oih the 2 stroke is the only american engine that is worth a shit! fucking hate joke oh there fun to destroy they got some use, haha.
well a 4 joke stroke is fun to bash with a sledge hammer!
The slit in between the cylinders is a point of failure (for a boosted engine) not an increase in reliability. I've replaced shortblocks for nearly 100 Ford Ecoboost 4 cylinders that had coolant consumption CAUSED BY THE EXACT SAME SLIT!!! In May Ford released a revised block that had a hole bored between the cylinders that connected to the coolant passage in the cylinder head rather than the older slit design. Mark my words, that slit is a death sentence if you run high boost!
Good point. The new GM 6.6 gasoline truck engine has a hole drilled at the top of the cylinders for ring pack cooling.
Will be interesting to see what this costs as a crate engine. Hopefully they start to show up for sale out of recked trucks for a better price that coyotes. An engine can only be as cool as it makes sense.
Interesting that the top compression ring land has a steel insert on the piston, should equal many years of durability.
Im a simple man. I just want this in my sn95 in place of my windsor.
I want one for my obs haha
I was thinking about my Panther
In a perfect world I'd love to swap this into my 97 Thunderbird
i wouldn t knock the windsor too hard
Tilt it upside down and run oil injection. My OMC Johnson v8 2 stroke can do this and im sure this 7.3 can. im getting some ford v8's from a junkyard for my dry sump oil injected 2 stroke oil experiment. I will be using Motul 800 2t for my experiment. i cant wait to try this and will it survive? lets see?
R.E. ………..great job , Im old so tell Ford enginners to send 6,, 7.3 s to Kasse and the Gliddens and big check for both and get out the way so they can make POWER !!!!!!!!!!!
Boss nine heads would be so cool on top of that block!!!!
Yes jon kaase needs to build one of these lil monsters
I like how people point out Kasse and Glidden as great Ford engine builders (they are) but nobody gets more power per CI NA than the Engine builders in NASCAR 358 CI 850HP on 99 octane unleaded is pretty stout. Plus they run for 500 miles not 8 sec.
Thanks for the great video very informative thank you
Built for strength and longevity I like it a lot👌🏼🏁
J Smith the first gen had problems but they have been resolved, not like government motors type of problems though lol
@J Smith agreed, gm literally forgot how to make engines that run properly. Ford seems to be the only one that can figure out how to make a turbo engine that doesnt shit itself when worked hard
You wan Ford reliability, look at that Barra i6. Sadly they're out of production and big externally for a 4.0/245cid.. but damn if they can't make power
@J Smith what don't I know? Hmm? That the Barra i6 are capable of street power levels in the 600hp range? That they're reliable, or that they're externally large? I mean, I have one sitting in the back of my truck.
@J Smith you spelled ecotec wrong
What is the maximum overbore you can get with that production block? I am thinking for high performance applications you could weld up that coolant saw cut in the deck?
grat vid man i would like to know what size the mains and the rod journals are also bore thickness
Finally Ford got smart and built an LS style engine. I expect to see a bunch of these in the future.
LS style do you mean because it's a push rod V8, they've been around about 70 years.
Ford built the original LS/Cleveland engine in 1969, the Government Motors version didnt come till after Fords patent had expired.
Great potential in those ENGINES
They need to sell that as a crate engine but with an aluminum block.
People going bananas on the horse power comments for the stock crank. I think he was talking about turbo. Obviously centrifugal is harder in cranks. But it’s common for oem coyote cranks, ls cranks and even Honda cranks, all of which are forged, to make big boy hp. Just bc someone may have thrown some parts together and didn’t check squat and they grenaded their stock ls or coyote crank doesn’t mean it can’t be done or isn’t done all the time by real builders. The stock forged units are very good. And the blocks now days are also very good. I forgot to mention, many gtrs out there making north of 2000 wheel use a stock crank. Anyways those pistons look like mahle power pack 26 cc units aside from the compression ring insert. I am super pumped on this engine. I think this engine with a piston and rod upgrade will be strong enough for most of us knuckle heads. Very happy to have a ford pushrod engine that you don’t need to dick around with aftermarket crank and cam sensor setups etc. Wish ford would get away from dumb coils and go to a smart coil. But that’s just bc I don’t want to buy a coil driver to use the stockers lol.
At 5:00, don't like the coolant chambers/passages hidden and contained within the front cover, I see a direct path for coolant to enter the oiling system...
Great Vid, I just got the 2021 F250 7.3! Posted a vid on my channel of it as well. It's certainly a Super Duty!!
Awesome engine but how do you lock out the variable cam timing?
What does the crank weigh and what size are the rod and main journals. This is really going to be the new
go to engine for racers wanting to put big power in their Mustangs etc. Probably giving the LS a run for
it's money.
So odd question and I know it’s been 2 years but, from the one y’all cut apart, do y’all have any of the pistons and con rods from the engine that you’d be willing to sell just one? Cause I want to make a piston & timing set clock
That "saw cut" between the bores seems problematic from a boosted application like Ultrastreet that they mentioned. Not much room for the headgaskets to seal. Thoughts?
I already put in my order at the local junk yard.. When they get 1 in call me.. I still can't get over the 1800 hp comment 😬😲😎
Ya.... I have a little struggle believing that block will hold that for any length of time. Mains and crank look great but that slit in between the cylinder walls was a performance mistake. There will be sleeves coming out for this I guarantee. At that point I could possibly see 1800.
Not trying to be that cold water pourer tho🤣
Your going to pay a fortune
Will this fit into a 1969 mach 1? Not looking to ditch the shock towers. I know its smaller than a coyote but slightly bigger than a small block... was planning on a 427 Windsor stroker but this might be the way to go...
how tall are these motors with the stock intake? I can't seem to find a height measurement anywhere.
Find out what the valve spring pressures are PLEEEEEASE 😁
I think his stroke recommendations are way conservative, I would concur that for higher boost 4.1-4.2" stroke is probably for the best. Remember this is a 9.65" deck, an LS is a 9.2" deck, they run high boost on a 4"-4.1" stroke LS prettry regularly, a 3.622" or 3.856" stock LS/LT or L8T stroke is probably a better idea for over 1000-1500hp+ regular racing use, however for N/A work aftermarket 9.2" LS are frequently run with a 4.125"-4.25" stroke. I have seen than Callies is coming out with a 4.6" crank for the Godzilla which I am guessing is for n/a application. I figured with a 4.225"(0.005" over hone) bore and 4.6" stroke you can have a 522ci Godzilla and I would guess that with a shorter rod to allow more piston thickness and that ample cylinder thickness 1,000-1,200hp operation with boost or nitrous should be safe enough. 9.65"-9.2"=0.45"×2=0.90"+3.975"=4.875" So there's no reason even at that stroke with the added deck height that the rod can't be shortened a little if necessary and still allow at keast equal piston crown to what an LS with 4" stroke with moderate boost has. I would imagine that a stroker Godzilla should be able to be built with 800hp+ n/a and make 2,400hp+ on 3bar no problem, especially considering that a rod and piston engine with head work can make 750+hp already. Shame Ford didn't sneak in an easter egg in the Godzilla block design, since it has a 4.53" bore spacing, where it has FR9 Nascar headbolt pattern allowing one to buy a bare factory Godzilla block for $1,500(they were $995 for a short time) and put a set of cheap used Nascar FR9 heads on it. I still think Dart or someone is missing out on a goldmine if they produced affordable cast iron(instead of CGI) blocks (possibly with a taller deck for strokers) that can use all the cheap used Nascar R07 and FR9 heads and accessories. With the wide bore spacing that would mean much larger than the 4.185" bore also, surely more like 4.250"+ bores, which means 371ci instead of 358ci with a standard used NASCAR 3.25" crank and could mean 454ci with a 4" stroke at standard deck heaight without oil sprayers in the way and 511ci+ with a tall deck and a 4.5" crank, which are also number a Godzilla could be built too.
Looks strong don't like chain driven oil pump but every thing else looks solid horse power and torque will tell the story
don't know how i feel about that saw cut between the bores, metal looks pretty thin.
This bottom end with some sleeves , rods, pistons would be ready to send to 2000hp
What is the cost factor of one of these 7.3 to swap out and but into an 83 F350 4x4 with mods done to make more power for pulling a tailer?
I just bought a Super Duty with the 7.3. Had a 6.0 Powerstroke. I want to dump the oil before 1000 miles. How soon before I can run full synthetic oil?
Pretty similar to a LS based engine. I bet itll make massive power.
But a lot beefier
how hard would it be to get it set up to run on E85 ?
People have no idea that the 7.3 was developed as a replacement for the 6.8L V10 in E-Series cutaways and stripped chassis applications. The fact that Ford decided to make it an option in the Super Duty is strictly a bonus.
speaking of boat anchors, just out of morbid curiosity how does this compare width/length/weight to the 8.8l?
What type of crank is it flat or cross(sorry if it’s a stupid question)
Do you think Ford will offer this engine in different displacement configurations? I wouldn’t mind a 400ci or something similar that my 4R75 can live behind. Just saying
Guys will ford put a detuned/ smaller version of this motor in the mustang (eventually) or stick with the high revving yote?
Do you have any info on anyone who is developing items and installation platforms for all things 7.3 Godzilla as I want to install one in my 02 GT.
Oil filter right next to the pan....finally ford made it easy to do an oil change!
How did you guys hook up with a 7.3 so soon? Glad to see a good jump into the aftermarket so early in production, but it’s gonna be several years before they turn up in salvage yards for any reasonable price.
we all work or worked for Ford...
Motorhomes my friend
atom atom how bai it disassembly manuals? How do you guys get those for such a new engine?
Several years?... Your forgetting about crashed trucks. Im surprised there's not dozens on eBay yet
Brian Wolfe was Chief of Product Engineering before he retired....I am responsible for Ford global crankshaft manufacturing.
I didnt see anything cast into the block to keep the cylinders stable to the walls of the block? i think ford focus rs had a problem with cylinder wall flex related to this?
What's the bellhousing pattern on this? BBF or the same as the diesels?
i would like to know about the motor mounts, we all know this motor shares the same bolt patter for the bell housing of a 4.6 and the 5.4, see I am aiming at putting a 7.3 in a 05-09 mustang, big motor little car, like my dads 70 boss 429.
Would be fun if Ford threw this in a new version of the Mach 1!
428 cobra jet ;)
Would be to front heavy, otherwise cool idea.
@@knutendreringhagen289 just give it a nice set of springs!
Ford did iron block DOHC 5.4s WITH blowers on top of them in mustangs for a few years. This engine being a push rod engine carries the weight lower and would be lighter than an iron 5.4 even without the blower.
Yeah supercharged 1100 horsepower come factory with some sticky Mickeys
I would like to see a little bit of a beefier timing chain. I like the look over all though.
It's really overkill in the strength department and is only steel because its the cheapest way to get the job done. It also transfers significant harmonics to the valve train. The best timing chain available is actually a rubber belt w/ adjustable aluminum gears. the timing belt's unbelievably super thin and narrow. It's a "jesel belt drive" and costs 1500$ for a Ls. Once u see this in a 4000 hp engine your opinion on timing chain girth will change
@@brentiaconelli6484 I am familiar with a belt conversion. And no it doesnt change my opinion. I would like to see a bigger chain or double roller chain for this application. Harmonics are not a issue. Double roller chains have proven their dependability for probably trillions of miles or more. What it really boils down to is ford did the math. The can use the little chain and it will make it out of the warranty period. Then on top of the that they are going to save $15 per timing chain. Multiply that by 500,000 units and they saved 7.5 million dollars. It was one way they saved money, just like plastic valve covers, Plastic intakes thinner castings etc...
coolant flow? why ford hasn't done it this way on other trucks, 6.7, 5.0, 5.4? Looks to me a design flow.
Finally a NOT modular engine. (Coyote motor is good too). Chevy has owned hot roding and swaps for decades now, and too be honest the ls motors are beasts. But I think we finally have a good competitor. I look forward to seeing what the 445 can do.
Ford for life
this engine would look so good with Individual throttle bodies
Why couldn't they have installed a double roller timing chain with a tensioner and guide? I'll be waiting for that failing here at the shop
No freeze plugs?
So I noticed in your Fox Body swap you’re runnin’ the 10R80 behind the 7.3. What are you guys using for power train management?
We're working on a solution for that.
@@revanevan Since there is so such ECU ready to go, I think the 6R80 would've been the way to go. But far be it for me to criticize your work. I'm just happy to see such a quick jump start putting the 7.3 in something less than 7,000 lbs. Lower profile intake is a must as well. Keep up the great work!
You guys aren't concerned about the saw cuts at the head gasket surface ?
Joe Nobody doesn't look like they are deep enough to cause any weakness. Look maybe 2mm deep.
Any updates on the control packs and wiring
I'm just curious what levels the powdered rods could go to? It sucks that Ford uses them in things we want to race. I'm someone who's just curious because I'd like to know if the thing would hold up to some boost right out of the junkyard in 10 years. Or if it's going to require new rods for anything more than stock power levels.
Only thing I don't like is the plastic looking timing chain guides and the oil pump chain driven with a big plastic guide looks like weak links to me for high end stuff. Rest looks strong af though.
Can it be stroked out to match the bore?
Why won’t they bring the excursion back? It would sell very well the SUV market is big right now I would love to see one with this 7.3l and they would be the only ones with an actual work capable diesel option.
Hey bro any hard facts of the bore size and stroke length? I heard 4 inches stroke.
I trying to simulate the potential power NA and single turbo application.
Bore 4.22-inches x stroke 3.976-inches
@@akman1931 so its roughly a 107mm bore and 100mm stroke. Slightly oversquared. Destroke it and it can be rev happy.
Hopefully VMP can make the Odin kit a direct bolt on for the 7.3L then we can be ripping in 1000bhp trucks at the drag. And still haul the load daily.
Love the channel Evan and all the content! I have to ask if you saw the end of MM&FF coming before it happened? Really sucks I had a subscription since 1993.
Unfortunately, I did see it coming. Really stinks though. I'll just have to keep the spirit living here. Thanks for subscribing and watching.
@@revanevan mmff was my car Bible. I read all my issues several times. Hated school and barely graduated with a 2.0 GPA but ask me anything about any Mustang or Ford and I got you!
Any updates on the 7.3 in foxbody?
Other than emissions is there much of a benefit to VCT on a single cam?
Yes. The cam phasing can be varied to broaden the torque curve. Advance the cam at low speed for more torque. Retard the cam at high speed for more power.
