5.0GN tow

I really like the looks of this engine for big load moving etc, based on what Ford has released it's more like a replacement for the old 534ci SD V8 they made from the late 50s to early 80s. It's a low RPM slogger of an engine. That engine was a direct gasoline powered competitor for engines the old 270 Cummins, 6-71 and 8v71 Detroit engines etc. International also made a 549 gas engine too. Ford is just applying modern tech to a similar concept. Those old gas v8s were known to be able to handle duty with 80k GCWR trucks and some guys were running them in 100k GVW dump rigs. Granted they were mostly lower speed workhorses, but clearly the new 7.3 will have almost double the HP of the old SD V8 and more torque too. So 20 to 25k towing seems like a given for SD pickup applications.

Based on all that, not sure I see a real application in it's original form in the raptor. Maybe new cams and valve train etc, but a pure low RPM beast like it is now won't make a lot of guys check that box on the option sheet.

It should go in the ranger. ��

oh for crying out loud. And there's a 17000hp push rod engine in some boats too it does run on diesel though.

Biggest reason you will see this lower RPM, pushrod mill in a HD truck is about long life operation in low and mid RPM band - while needed to provide more than 400 ft lbs of torque and I bet the torque is higher than the HP when done. Without DOHC, VVT, and the like you remove some items that cause issue with many hours. Not miles - hours. the long chain necessary for DOHC, or chains is some cases - tend to stretch and warp with higher torque demands. SO making all that running gear as small as possible is a good move.

ALso IIRC that mercury marine engine runs a gear drive timing set. Anyway time will tell how this goes about. I would wait for the version that has dual injection system as it will be more effecient, and maybe they put dual spark plugs on there. They should.

17k hp, are you talking about a freighter?

Napalm

I think it's in a cruise ship but yes. again the idea that all engines must be DOHC and VVT is a bit absurd there are reasons to avoid all that too.

I mean ideally - we should all have a turbine under the bonnet if you want to get full on systematic efficiency on deck.

With automotive engines, DOHC, 4V, and VVT engines have higher performance than pushrod 2V engines! NASCAR is the only race series that doesn't allow DOHC, and 4V, maybe it's because Chevy doesn't have a DOHC, 4V V-8.
Can you even imagine a pushrod, 2V engine running the Indy 500?

exactly what I was getting at. I am guessing 425 to 450HP, and 500-550lb-ft. It will peak the torque around 1900 and keep it until 2600 or so, and probably peak HP around 3 to 3300. Almost like a diesel or the old 300I6. It's a work engine, not a race engine. Long hours of hard work at heavy percentage loads and happy doing it. My dad drove old ford city trucks with the SD V8s in them and they were exactly this way kind of engine.

this is an interesting engine. for one thing its push rod, thank god ford!!! ford has only done stupid overhead cam engines that are way way overly complicated, while chrysler has the hemi and GM has the LS which are more reliable, simpler, put our more grunt down low and quite simply are better engines, than the 4.6,5.4, 5.0 or the 6.2. I view this 7.3 as ford finally realizing over head cams are just a bunch of BS that overly complicates the engine. I listened to the ford engineer talk about this new engine. it sounds like this is only going to be used in super duty trucks and up. its not made or intended to be used in the f150 or even more so mustangs. I think CAFE standards are the reason. I also think that is why the 6.2 was trim limited, ford couldn't sell a bunch of them, I bet they wanted to. if you look at the dyno sheet the 6.2 blows away the 5.0 in power where it matters.

and so does the 3.5 eco...the differences in torque between the 6.2 and 3.5 is negligible. also how do you know what ford wanted to do?

and i wouldnt call the hemis reliable...unless you like an engine that eats lifters. if over head cams are a bunch of BS then so is fuel injection..lets all swap back to carbs!

also for what its worth...fords little 2.7 outperforms the 5.7 hemi and 5.3 LS

Takeda

The Hemi and GM V-8s are the ONLY production engines that are pushrod, and 2V! DO a google on "AFM BLOWN ENGINES", and you will see how reliable the GM V-8s are! Also google the "HEMI TICK".
