That makes it more powerful than any Ford 4.6L V8 ever offered in a pickup, more powerful than Toyota's 4.7L V8, more powerful than the outgoing GM 4.8L V8, and as powerful as the GM 5.3L or Ford 5.4L of just a few years ago.

So if 300hp is "adequate at best in a full size truck" then any Toyota Tundra older than 2007 with its 271 horsepower (and 313 lb-ft torque) 4.7L V8 must be truly unacceptable.

My 2000 Camaro SS with the 5.7L LS1 made "only" 320 hp (up from 305 hp in a lowly Z28)

The Camaro has 10.3 lb/hp, the early Tundra has 17.7 lb/hp, and my F150 (with its 360 HP V8) has 15.8 lb/hp. However, if the F150 only had 315 HP that would swing the pendulum to 18 lb/hp, worse than the early Tundra which was not known as a hot rod. Comparison of power numbers is POINTLESS without considering the weight of the vehicle.

Not only do I not think 300 HP is adequate in a full sized crew cab 4x4 truck, I voted with my wallet. For the same money I was comparing the 4.6L Crewmax Tunda (18 lb/hp) with the 5.0L SuperCrew F150. The 5.0 returned the same MPG but with 50 more HP, which was definitely noticeable when driving the trucks back to back. My wife does a lot of driving on 2-lane backroads with heavy semi traffic, roads where having plenty of power to pass provides an extra margin of safety. For a vehicle that my family would be riding in, it was a big deal to me. So for my needs I absolutely stand by my "adequate at best" statement, I would not consider a 300 HP V6 powered full-sized crew cab truck.
All I'm saying is that ten years ago (2003) you simply couldn't get a 1/2 ton Ford (or GM, or Toyota) that made even 300 horsepower, even with the largest V8 engine choice. And people thought they were more than adequate, even in a 6000 lb crew cab, even for towing.

The new Dodge V6 with its 8 speed auto returns 25 mpg EPA freeway, and makes more horsepower than any 2003 1/2 ton, while having more mechanical leverage with its 8 gears to choose from (vs 4 speeds automatics in any 2003) to negate the torque differences.

The 4.3L V6 in the new GMs will be even a little more powerful than the Dodge

The Camaro was simply an engine output reference. Remove its mention and my post is still valid.
