It’s the ultimate engine shoot out – seven streetable high horsepower “elephant” engines fighting it out for top honors as the ultimate Chrysler 426cid Hemi. Playing center stage is the COMP Cams® R&D engine dyno facility, which will host the first ever Royal Purple Hemi Engine Challenge. Featuring an assortment of 426cid engines, participants will create power-packed Hemi engines, using the most creative assemblage of parts and technology at their disposal in an attempt to generate the ultimate in horsepower and torque for the dollar.

For this first of what could become an annual event, Mopar Muscle Magazine, creator of this contest, chose to feature the 426 Hemi. All of the parts used in the build-up of these engines must be available over the counter, through any supplier. Each engine will be scored using a simple composite system that, when tallied, will demonstrate affordability of Hemi horsepower through a cost per horsepower final result.

“With all of the buzz surrounding the modern Hemi engine, we felt that it was great to be involved in an engine contest that compares legendary 426cid Hemi engines,” said COMP Cams® Marketing Manager Chris Douglas. “We have done a great deal of development work with the new Hemi 5.7-liter engine, creating new camshafts and valve train parts that greatly increase horsepower and torque, but many enthusiasts forget that we have a great number of high-tech camshafts and valve train parts for the classic 426 Hemi. We are pleased to be involved in this inaugural event.”

Winner to be announced at this year's PRI Show taking place in Florida.
