As we finish up the 2008 Amsoil/Mopar Muscle Engine Challenge, we'd like to thank all of the engine shops that participate in our contest not just this year, but every year. Remember that the contest is open to all competitors, big or small, so if you feel like you have what it takes to win a dyno challenge, visit for all the details. We'd also like to thank all of our sponsors, especially Amsoil as the title sponsor, and also Comp Cams for donating their facility and personnel, making our contest possible.

Looking forward to next year, our Engine Challenge will feature a low-deck big-block, with Edelbrock Performer RPM cylinder heads. There isn't a cubic inch limit for next year's contest, so we're speculating that horsepower numbers will be impressive. Be sure to follow along as we once again try to break Comp's dyno with massive Mopar horsepower! And for a behind the scenes look at the 2008 contest, visit our website for additional pictures and video.
