The 2007 Mopar Muscle Engine Challenge

Of all the technical subjects we write about here at Mopar Muscle, our annual engine challenge always gets a great response, and why not? Where else can you see eight of the country's best engine builders compete head to head exclusively with Mopar iron, with true dyno numbers to back up their proven combinations? Since our challenge factors not just the power of each engine, but also the cost of the each engine's parts, the builders have to be creative to be competitive.

This year, our engine challenge features the small-block Chrysler powerplant, and we've already chosen the eight engine shops that will compete. We look forward to seeing what kind of numbers their potent LA engines will produce.
