Jim5.0,
Yep, the 2015 Mustang gets a 4cyl 2.3L Ecoboost at about 300 HP. But the 3.5L Ecoboost is going to continue in the F150 and I hear that for 2015 the F150 will get a all-new Ecoboost, a 2.7L (Nano) V6 that is even smaller and lighter than the 3.5/3.7L family of V6s. So there will be two V6 Ecoboost engines in the new 2015 F150.
I agree that both and GM will continue to create more power and even better FE in the near future. And I agree that NA V6 engines will be around 350HP. But the key for the 3.5L V6 Ecoboost is that 90% of peak torque, so around 400ft-lbs, is available from 1700 rpm through 5500 rpm. You just can not get that level of flat torque curve from a small displacement NA V6.
I also agree that since the conversion of a Mustang to a F150 3.5L Ecoboost engine and 6R80 will likely cost you about $10K to complete, that just spending $10K on a 3.7L will likely get you the same power and durability, or even more. I am not sure about the FE results, but i am certain that there are several good options to equal the power and durability of the 3.5L Ecoboost.
Personally, I prefer doing a swap using a factory-proven powertrain where I know the expected results can be achieved, that's all, just my thinking.

I was reading an article about the 2015 F-150 this morning. It talked about running the EcoBoost engines in Baja 1000. I also remembered reading about this testing a couple of years ago when they were first coming out. If they can hold up to Baja racing, I'm sure they can handle a 20 minute track session.

There is no way a Baja racer is running production stock cooling. Especially if forced induction is present. To keep an EB 3.5L Mustang cool and at least sort-of all Ford, you'd be hoping for uprated cooling to show up in the FRPP catalog.

Good point. Baja is still hours of grueling punishment. Its one hell of a torture test at full throttle... and they did that to a motor that had been driven 150,000 miles.

& they also tore the engine down and everything was still in factory spec/tolerance's.....thats insane.
