There is not any arena of performance or power in a street vehicle that the 5.3 is not superior to the 454, Towing, speed, horsepower, reliability, performance, i've driven all of them and i cant think of any reason why i would take a 454 over that 5.3, the enginering behind the newer motors and the engine management system that comes with it cannot be equaled with a carburetor and 20 year old technology.
