Is there a reason the RT stock with a 5.7 can't come with 425 horses? Is it to cut costs? I'm just wondering how a 3.7 liter 370z gets 332 horses. The 5.0. has 420 horses from a smaller displacement, do they tune the 370z and 5.0. from the factory or add certain performance parts? The SRT is a 6.4. so 470 is expected lol. I just wonder if the 5.7 has the potential to have a lot more power stock? I love my Challenger but I always wondered if they just underated the power cause it feels alot faster than the 370 horses that is stated by dodge and it weighs 4k pounds so I wonder if it's underated cause no car this huge should move this quick lol. Especially with only "370" horses. My main question is how are smaller engines able to produce such power? and does the 5.7 have more potential than most people think?
