At one time, if you wanted big horsepower in your Mopar muscle car or truck, your choices were limited to a big-block swap or a coveted Hemi. At the very least, you need different engine mounts, K-members, transmissions, headers, etc. - and Hemis have never been cheap! But now there's another way to get more horsepower: boring and stroking your Mopar small-block to get more cubic inches - up to 476 cubes! The small-block Mopar is one of the easiest engines to increase displacement without extensive modifications or specialized machine work - the engine was practically designed for more cubes. This book shows you how to get that big-cube power, then it shows you how to optimize the small-block's other systems - induction, heads, valvetrain, ignition, exhaust, and more - to make the most of the extra cubic inches.
