Most of the time we feel every vehicle in America needs one of these engines: a 7.4L 454ci big-block. Not just because of the horsepower, but because just saying "big-block" sounds cool. The engine is fed by a 770-cfm Holley Avenger carburetor and an RPM intake manifold. A set of Hooker competition headers helps the big-block breathe easier, and two Optima RedTop batteries keep everything charged and the winch running strong.
