Ford's making the 7.3 again?


Sort of...but it's a gas 7.3. Probably a bit of marketing off the love of the old diesel 7.3.


The following combination of bore, stroke, combustion chamber design and compression ration enabled Ford to produce the best horse power while keeping the A/F ration as close to stoichiometric as possible.

7.3L just worked out to work the best.


I'm sure it doesn't cause problems but if there was something magical about that combination of design criteria...everyone would be putting out a 7.3L gas engine.

Bionic gave good advice. Buy first on the seat, then price. You really cannot lose with any of the the big 3.

Define “Struggle” please?

If you mean it slows down on hills and you have to get the RPM’s up to maintain speed, you will have to do that with any Gas V8.

Thanks!

After several struggles in the mountains I've decided it's time for a new truck.
My old truck has been really good but new trailer is pushing it.

Current truck is 2004 Ram 2500 5.7 Hemi pulling 8K trailer, struggling mightily on the big hills with a bunch of junk in the bed.

I'm going new here but stuck on the 6.4 Dodge or the 7.3 Ford.

I'm a gas mechanic so no diesel please....yeah I know.

6.4 or 7.3 ?


Then you want a Ford, period. Currently have V10 in Class C Motorhome but towed 5th wheel for many years with 7.3 L Ford turbo diesel and crossed the Rockies many times including the Beartooth highway in Montana towing 10K trailer. Climbed every grade on the Beartooth in overdrive never downshift for any reason. Still own the 96' 7.3L truck which is now ledgendiary. Sadly the EPA and the cost to Ford from engine manufacturer international was to much for Ford to keep in market therefore this engine no longer available.

That's why they went with 7.3L and not 7.1 or 6.9 or 7.4 or 7.8.

That's what they try to achieve for every engine regardless of displacement.

Sure they try to achieve the ideal operations but they can do that with just about any displacement.

If they had a much loved 7.2L, you can bet they would have reworked it during design to be 7.2L.

Teacher! Teacher! I know I know! It’s a 7.3 because no one would know what a 445.47 cubic inch is?

I guess you're right. It ended up being a 7.3 due to their love of the old cornbinder engine.

I was only going by what the engineers said who designed the new 7.3.

other than liters, unlike the original 6.9/7.3 v8 idi diesels from ihc, they made great gas versions from those blocks too! that will not happen with todays motors no matter how you slice the cake. even IF ihc could have still made the T444E 7.3 version, which had 2 parts left over from the IDI version. Todays version would need to be different also due to as noted, EPA for both sound and air pollution standards. No different than the current GM 4.3 is not the original block design from the mid 80s, ie a 350 with 2 cyllinders lopped off. That block design ended with the vortec 4.3.
As noted, a good engine builder desinger can make ANY engine size run great. Question becomes, does it meet the end spec needed for what it is being used for!
