$4200 option over the 6.2? That's half the cost of a 6.7 option.

Yeah, but likely less than the labor cost of having the cab lifted off the engine for major 6.7 service.

The 6.8L V10 has driven the RV industry for the last 20 years... in Class A motorhomes, Class C motorhomes, Class B vans, E Series ambulances that rush us to the doctor, and F Series trucks... from the F-250 all the way up to the F-750.

For over two continuous decades in a row, the overhead cam 6.8L Triton V10 has provided the power and proved itself... without a lot fussyness or fan fare.

Where's the love?

I don't think anyone said anything negative about the 6.8...but time marches on.

Hopefully this engine will be a worthy successor.

Carbed big blocks drove the RV industry for years before the 6.8 came around, but no one is looking to go back to those.

I only have 8000 miles on our new Class A but so far I love the V10. I rarely read of any catastrophic engine failures. I hope to put many many miles on mine.

I am assuming that the F53 will eventually use the 7.3 but I wouldn't be surprised if Ford still makes the V10 for the F53 for several more years.

That engine is one of the best Ford ever ever made. Plenty of high revving power and absolute great reliability. I think Ford could have improved the Class C Chasis and the Class A chasis for quietness and ride and I don’t under why they haven’t except for max profit.

But that motor is stout, yes it’s horrible gas mileage and it takes a while to break one in but I’m still a fanboy.

The 6.2L stays as the base engine in an F250 only, and comes mated to the 6 speed auto. The 7.3L and 10 speed will be the base in the F350 and up.

I don't look for the power numbers to be a huge increase over the 6.2 but numbers aren't the only part of the equation. It's the total package that counts and unless this engine has some unforeseen problems I think it's going to be a home run for Ford. This engine looks to be a well thought out simple engine and should be able to pull some heavy loads.

The 10 speed should be a plus also. When my 6.2 shifts down to 3rd there seems to be a big increase in the rpms so I think the 10 speed will handle the same situation better.

I'm looking forward to seeing and hearing about some real world reports on these trucks.

Just another engine option between the 6.2 and 6.7. It will cost more then the standard 6.2 but this looks like a great engine choice for those not wanting diesel. I’m still looking forward to the testing of this and the GM 6.6. I like the GM of course being a LS and bulletproof. But this new 7.3 also looks good so it’s good to see the HD trucks getting such nice gas upgrades!

Another example... the new 6.6 GM gas has a 10.8 compression ratio. And no question about how the calibration prevents detonation.

Direct injection, better combustion chamber design, better cooling systems, VVT, and knock sensors/engine tuning. They have a lot of control over combustion chamber pressures and cooling these days.

Lots of engines running those sort of compression ratios on 87.

I doubt the engineer would tell how it is tuned. He would just give a canned response mentioning some of the things I put above.

This 7.3 really does look like a modernized big block. Big canted valves, big exhaust/intake ports, etc.

And if you look at the shot of it sitting on the stand next to Andre, it seems like a pretty small package (considering the displacement and application). The modular motors are huge, super wide with the overhead cams. I'm really digging this engine so far.

Great job; Ford finally went to the KISS theory! I think this engine will be awesome and a fantastic alternative to the complicated 6.7L diesel. I had to chuckle a couple of times watching the video; many of the points covered and the coils mounted to the valve covers reminded me of the 5.3L in my 2001 Yukon! :B

Likewise, I wish they (meaning Andre, Mr. Truck, and the like) would have asked the engineers a LOT of questions that they clearly didn't know enough to ask (and I don't mean HP or TQ), rather than listening to themselves talk. Andre is a lot better at listening then Kent (Mr. Truck)... but both of those guys could learn a thing or two from several members I've seen posting here on RV.net over the years... about what the kinds of issues that concern the consumers who actually fork over their hard earned money for these trucks, rather than make a career mongering manufacturer freebies to run up and down Ike pass in media sleds.

I will guess 436/500, $2500 option with the 10 spd, and runs on regular gas. If it's meant to be a fleet truck engine, it needs to run on regular. Wish they would have asked the engineer about the fuel.

If it's a combustionable fluid I'm sure this engine will run on it just fine.

Looks like a jewel...
