First Place
Prism Racing

As a newcomer to our annual dyno contest, we were all curious how Prism Racing would perform. With a big-block displacing 406 cubic inches, the Prism entry answered all questions as engine builder Darren Tedder took advantage of no upper rpm limit set by the rules and spun his big-block well over 8,000 rpm on his final pull, making 647 horsepower for a score of 1.593 horsepower per cubic inch. This purpose-built dyno engine performed well, turning the highest rpm of the contest, but Darren did comment that he would make a few changes before putting this engine in a street driven Mopar. Prism Racing's owner Daren Tedder would like to thank all the employees of Prism Racing, as well as Ted Fischer for helping with this project. Additionally, Darren would like to thank Wills Machine Service who turned his crankshaft three separate times while he waited, helping Prism achieve a top finish in the 2011 contest. We congratulate Prism Racing for winning the 2011 AMSOIL/Mopar Muscle Engine Challenge.

Second Place
T & B'z Race Engines

Another newcomer to our contest is T & B'z Race Engines, who nearly scored a win as their 426 cubic inch big-block made 676 horsepower for a horsepower per cubic inch factor of 1.586. Engine builder Tom Foley says he and his wife Brenda treated this like any of their customer's engine builds, putting together the best package for the money. They did their research well, coming the closest to hitting our budget of $5,500 and bringing a real-world big-block that makes peak power and torque at a very reasonable rpm. Tom and Brenda would like to thank their kids, Leeza, Lez'lee, McKenzy, and Dempsey, not only for their help, but for tolerating the extra time their parents spent at the shop working on this project. T & B'z also says they couldn't have performed so well without the support of Engelking Dyno Service and German Valley Machine, and would also like to thank Cometic, Total Seal, AMSOIL, and especially Comp Cams for hosting the challenge. We congratulate T & B'z Race Engines for their outstanding performance, placing a very close second in the 2011 AMSOIL/Mopar Muscle Engine Challenge.

Third Place
H P Engines

H P Engines is another engine shop that made its debut appearance in the 2011 Mopar Muscle Engine Challenge. Engine builder Hollis Page decided that a big bore, short stroke big block would have an advantage, and built a low-deck big-block displacing 406 cubic inches. Deciding to build a real street engine and not just a "dyno-mule", H P Engines used quality parts and stayed well under our $5,500 parts budget. Making 608 horsepower, for a rating of 1.50 horsepower per cubic inch, the HP Engines big-block earned third place in our 2011 dyno challenge. Engine builder Hollis Page would like to thank his fellow employees including wife Kim, engine builder David Klottz, and machinist Brett Gibson, as well as Liberty Engine Parts and the sponsors of our contest: AMSOIL, Comp Cams, Cometic Gaskets, and Rockett Brand Racing fuel. We congratulate H P Engines on their third place finish in the AMSOIL/Mopar Muscle Engine Challenge.
