What do you do for a living and what is your knowledge of internal combustion engines?

Great report!!!! Thank you!

All that on a stock f-150 + intake.

Your truck did great.

Just add tuning and it will have enven more power.

I have the 5.0L. But I really want the 3.7 becuase it is so capable. And it has 300+ HP stock.

I'm an engineer by day but on my spare time I race motocross and also drag race. I have built no less than 25 motors for my drag cars from the ground up and in my 29 years of racing motocross I have probably torn down hundreds of motors. I am more than qualified to suggest that running an engine near the limiter for any length of time is not a way to ensure long life.

Really, you want to give up 65hp, or more, as it us underrated, and even more torque? I how you were bring sarcastic.

The 5.0 would surely outperform the 3.7, and likely very better mileage while doing it.

I should have clerified my situation. I dont tow/haul that much.

Not to be the towing police..........but the tires on your TT are only rated for a max of 65 mph....especially at max axle load. Exceeding that speed is asking for tire failure.
Glad that the truck did well for you, but personally I could not listen to 6K for 10 miles. One of the reasons I got rid of my 5.4 was that 3,700 rpm was painful to listen to on the grades....

In an article about the EB's R&D testing, I read that they ran the engine from WOT for ten minutes then was let to sit for ten minutes 1,500 times without changing the oil once. Another test ran the engine at full throttle for 362 hours (15 days) straight and the engine and turbos passed with flying colors. If a similar boosted engine can withstand that and pass then I don't think 10 miles at 6,000 rpm would hurt the N/A 3.7L at all as long as it has sufficient cooling and lubrication. C'mon guys, this is Ford we are talking about here, not some joke Chevy. Even though I wouldn't want to hear an engine at 6,000 rpms for 10 miles, I don't think it will hurt it.

If the 3.7 was able to go as fast as I wanted, or could safely go, and it has lower Brake Specific Fuel Consumption that the 5.0, how would the 5.0 do it more efficiently? That is an old myth going back to the ****tier base engines having a lower level of engineering, and inferior transmissions. Not applicable to this scenario. Remember, I was getting the mileage benefits of the more efficient engine the vast majority of this trip, running 2400 rpm in 5th. Not bashing the 5.0, it is just not as efficient as the 3.7.
I test drove identical trucks, all 3 models, and the average over a mile on the same day, same stretch of road, the 3.7 was the most efficient, EB next, with the 5.0 about 10% back of the 3.7 @ 70 mph.

That's my thoughts as well. I have never worn out an engine, and I (especially when I was a little younger), treated an engine as abusively as imaginable. The only time I abused an engine to its limit was on successive 1/4 miles with a modded Dodge 318, and I overheated the oil. It developed a light rod knock. Consensus at the time was the oil temp wat the issue.
This trip was a on-off. 80% of 15-20 000 miles a year is usually highway travel, and on that alone the 3.7 saves over 10% on fuel over the 5.0 @ 70 mph.
