Fourth Place
MRL Performance
Jackson, Michigan
MRL Performance made a good showing this year, as their RHS-headed small-block turned in impressive numbers with unported heads, moderate compression, and a flat-tappet camshaft. Stating that the head flow of these heads out of the box was nicely matched to his Lunati Voodoo camshaft, engine builder Mike Liston proved it by making 1.372 horsepower per cubic inch from his over-bored 340 small-block.

The 340 Mopar was a popular choice this year, and engine builder Mike Liston of MRL Performance brought a powerful one to the 2010 contest. With a flat-tappet camshaft, this little powerhouse made more than 470 horsepower.
Mike Liston only removed the...
Mike Liston only removed the air cleaner and adjusted the ignition timing while in the dyno cell, completing all of his pulls in far less than the allotted time. This engine had a few trick parts but was basically bolted together with well-selected off-the-shelf items.
The MRL Performance entry...
The MRL Performance entry kept making power to above 7,000 rpm and had nearly 400 lb-ft of torque as well. We congratulate Mike Liston on his fourth place finish.
On the dyno the MRL Performance entry started easily and ran well, making well over 450 horsepower on its qualifying pulls. For the judged portion of the contest, Mike changed his spark plugs to E-3 plugs, but otherwise left his tuning alone. By adding a little ignition timing and removing the air cleaner during the judged pulls, Mike achieved a best scored pull of 472.9 horsepower.

B&G Speed and Machine
Bargersville, Indiana

As a newcomer to the AMSOIL/Mopar Muscle Engine Challenge, B&G Speed and Machine built a flat-tappet 360 for the contest. At more than 418 horsepower, their small-block Mopar made 1.14 horsepower per cubic inch.
The B&G team worked well together,...
The B&G team worked well together, quickly warming their engine up and making the required qualifying pulls to 7,000 rpm. With ignition and timing changes, the B&G entry made more power with each dyno pull.
B&G's best pull of 418.7 horsepower...
B&G's best pull of 418.7 horsepower was enough for a fifth place finish in the 2010 AMSOIL/Mopar Muscle Engine Challenge. We congratulate the B&G team on their performance and thank them for entering our contest.
B&G Speed and Machine built a solid 360 cubic inch Mopar small-block for our 2010 dyno contest, running their engine on the last day of the Engine Challenge. Though a couple of minor issues may have kept us from seeing the real potential of this engine, the team from B&G were professional and efficient, tuning their relatively mild 360 to well over 400 horsepower. These guys definitely made a good showing in our 2010 contest, and we look forward to seeing them in future Engine Challenges.
Sixth Place
Chenoweth Speed
and Machine
Morton, Illinois
Last year Chenoweth Speed...
Last year Chenoweth Speed and Machine finished second in our contest. Unfortunately, a mechanical issue kept the Chenoweth team from making the qualifying dyno pulls in this year's competition.
The Chenoweth/LaRoy team came...
The Chenoweth/LaRoy team came ready for action, but unfortunately it was quickly apparent that their engine was pumping water into a header. Having the least displacement, this engine would have needed to make 420 horsepower to beat Schurbon Engine and Machine.
Chenoweth Speed and Machine built the smallest engine for this year's contest, over-boring a 273 Chrysler for a total displacement of 279 cubic inches. Noting that last year the LaRoys made an impressive 1.6 horsepower per cubic inch, Chenoweth teamed up with LaRoy Engines for the 2010 contest, hoping to gain an advantage. Everyone was eager to see what kind of numbers this little powerhouse would make, but unfortunately the number seven cylinder was filling with coolant during warm-up on the dyno and the engine had to be shut down. As of this writing, we aren't sure what happened, but we'll update you when we go inside these small-blocks in future issues.
Do you have what it takes to compete in the AMSOIL/Mopar Muscle Engine Challenge? Remember, we accept applications from shops large and small, and even from guys building engines in their garages, so don't hesitate to apply. Everybody is a winner in our contest, and getting your company's name in front of our readers can certainly get your phones ringing. We'll announce the rules for the 2011 contest at the PRI show in Orlando, Florida, or a copy of the rules and application can be downloaded from www.moparmusclemagazine.com.
