The 2.7 is a marvel of engineering. It is nothing like the 3.5 except for both having twin turbos. Competing the 2.7 is like comparing the 3.5 to the Chevy 5.3,' - they are from different eras. Just wait until they make the 3.5 like they do the 2.7 with the cgi block and all.
2.7 engine build is the future. Period.

I'm waiting for a gen II 3.5 and a 10 speed auto.

5 stars dyno test puts it above the 5.0 in torque at the wheels and just below it in HP. The only real issue is lack of power above 4500 and fuel economy towing. If you are going to tow a lot, just get the 3.5. but for daily use and weekend camping trips or occasional towing it is just fine.

Oddly enough, that hp number for the 2.7 shows about 20% drivetrain losses, the tq would only be about 15% though (underrated on tq?) while the 5.0 comes out about 24% losses for both hp and tq.

If the engine is underrated then how can you determine drivetrain loss?
Lets be honest here. It is well ahead on torque (320/295 is how I read it) but farther behind on hp (260/295) (2.7/5.0 in both cases). I really wish they used the same numeric scale for hp and tq for the 2.7 like they did for the 5.0.

I don't know. I think the 2.7 falls short on hp because it runs out of steam at high RPM. I don't know if the turbos are small or they are limiting airflow. All I know is it has very good throttle response and tons of pull up till 5k rpm. then it just flattens out.

I agree, it reflects on the dyno as well. Its a truck engine it doesn't need to pull hard at 5000k. Climbing steep grades my truck stays below 4K when towing.
