Our Martini shot of the day came with the installation of the biggest of our trio of cams, the XFI 273. While it's the largest cam of the currently available series, it is relatively mild in specs by the standards of brawny street cams, measuring a comfortable 224/228-degrees duration at .050 inch. Power proved the potential lurking in the Hemi, recording a blistering 491hp peak at a jaw-dropping 6,900 rpm, while torque checked in at 417 lb-ft at 5,000 rpm. Does the new Hemi have muscle? With nearly 500 hp on tap from a stock engine with a street cam and headers - oh, yeah! View Related Article
