2005 Hemi Engine Challenge Update
|
Jeff Dickey and his team from J.D. Engine and Machine in Columbia, Missouri, brought this tunnel-ram-equipped, dual-Dominator-fed Hemi to the contest not just to compete, but to win. These guys can definitely handle working under pressure as they tuned their motor between pulls, making more power each time. If it weren't for some weak valvesprings causing valve float above 6,700 rpm, Jeff's numbers would certainly have been higher. Even with weak valvesprings, J.D. Engine and Machine posted the horsepower number to beat. How about 728.2 peak horsepower and 615.8 lb-ft. of torque! View Related Article
