I would suggest to every man, that is a true man, get the 5.7L Hemi! Awesome power. With a cold air intake, throttle body spacer, true dual exhaust with Flowmaster muffler and a power chip the truck is hard to handle. Pushing around 440hp. Ford and Chevy haven't got anything on that hemi.
Get rid of that switching back and forth 8cylinder to 4cylinder.
