40hp & 48 lb.-ft. boost for the 5.3! And the MPG is better than Fords V6 eco-boost!


355hp & 383 lb.-ft. Towing up to 11,500lb.

No specs on the 4.3L or 6.2L yet. The Vette 6.2L picked up 20hp so hopefully the 6.2 will be in the 425hp range.

Nice....I don't think there are many ecoboost owners bragging about mpg. I think most 5.0's are getting better mpg's.

Have to rev high for HP, booo....and under 300rwhp, wonder what the 6.2 ratings will be.

Jokes on anyone who bought their Ford or Chevy truck for the gas mileage.

Awesome. Now Just lose that ugly ******* step bumper.

Well if you get one with a painted bumper it won't have the step. That's just on the chrome bumpers.

X2 that HP is really high RPM's but the torque of over 300 for 2000-5000 is nice
