Promax Carbs And Performance Parts
Promax Carbs and Performance Parts was an alternate entry this year, agreeing to participate on very short notice when another competitor dropped from the contest. Even with short time, they managed an impressive 554.1 horsepower and 526.3 lb/ft of torque from their relatively mild 440.

Knowing time wouldn't allow an all-out 440, engine builder Ben Gorman freshened up his low-compression dyno mule, utilizing his combination to demonstrate the abilities of Six-Pack carburetion.

Built on short notice, the Promax entry was far milder than the other engines in this year's contest. As the dyno chart shows, however, this engine is no slouch with broad torque and power curves. We congratulate Promax on making the engine challenge and thank them for adding diversity with their Six-Pack induction.

Dyno operator Rich Smith kept things fair, making each dyno pull with deadly precision. We thank Comp for hiring professionals like Rich, and for offering their research facility for us to hold our contest.
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 moparmusclemagazine.com 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.
This year's winning team,...
This year's winning team, like all the competitors, used Amsoil synthetic oil in their engine and we're happy to report there were again no oil related failures during the 2008 competition.

Remember, these 440s made incredible power not on high-octane race fuel, but on Rockett Brand 93 octane unleaded pump fuel.
Be sure to catch a glimpse...
Be sure to catch a glimpse of the 2009 contest engines as the builders drop them off at the Mopar Nationals. Engine builders will be on hand throughout the weekend to discuss their engines or answer questions about your next project.
