It's no surprise that the new Hemi is an impressive power plant, and a worthy successor to its legendary namesake. From the pedestrian 5.7 all the way up to the new 6.4, the Hemi is more than a match for anything offered by Ford or Chevy. Credit goes to the cylinder heads and an efficient intake design for the majority of the power. The tremendous flow rate of the heads and intake allow the factory Hemi to produce prodigious power with mild cam timing. The Hemi is literally begging for more aggressive cam timing, but fuel economy, emissions and idle quality concerns all dictate mild cam timing for factory engines. Given the airflow potential, one route to improved factory performance is increased displacement. Chrysler took this route with the new 6.4 Hemi to the tune of 475 horsepower. If 400 is good, then 800 horsepower must be even better, and the only thing better than 800 is 1,000 horsepower. Are you starting to get the picture?
