How much horsepower does a 2004 Chevy Silverado 5.7 liter 350 have?

Answer 1

I believe Chevy Silverado in 2004 Comes in a Few Motor Sizes, but None include a 5.7L .

As per this link for example ( Though most sites seem to agree )

http://www.carsdirect.com/research/model-year?make=CH&modelid=55&year=2004

We see, for the 1500:

Engines: 4.3L V-6 195 HP, 4.8L V-8 285 HP, 5.3L V-8 295 HP, 6.0L V-8 345 HP

And the 2500 :

http://www.carsdirect.com/research/model-year?make=CH&modelid=2091&year=2004

We see only a 6.0L V8, with 300HP.
